Butterfly Effect

Butterfly Effect (버터플라이 효과) was a five-member girl group under K-Sims Entertainment. They debuted on April 23, 2012 with the single "Always".

Their name means a butterfly flapping its wings and causing a typhoon. Just like the real theory of the butterfly effect, they will cause a ripple in time.

Prior to their debut, the group appeared alongside label mates Before School for the commercial song "Lollipop" in 2011.

On February 12, 2019, K-Sims Entertainment announced that the company will pause all promotion for their artists and will be in a temporary shut-down, leaving the groups signed to them in limbo.

A few months later on April 23, 2019 Butterfly Effects anniversary Nallia announced that the group will move to a new company with Nallia's husband but that the company wasn't fully set up yet so they couldn't reveal too much about the company or their future plans.

Pre-debuts
The group was first mentioned by Before School in late 2011. Originally it was planned as a 10-member co-ed group consisting of Ana, Minchae, Kiki, Dohee, Daeho, JU, Minsu, T-Young, SeoSeon and SeoJeon from Before School.

The original plans for the group were scrapped and Nalllia was added to the final line up making it a 5-member girl group. Nallia was revealed in the “Lollipop” video, having been added to the group last minute many fans boycotted the decision to add Nallia and demanded the original lineup of the co-ed group.

In January of 2012, London Lee, CEO of K-Sims Entertainment, stated that the members Ana and Nallia would be releasing a pre-release single in preparation for the groups debut and that after the group debuted another unit from the group would release a song. Ana and Nallia released "How We Do" in March of 2012 then a few short days later Butterfly Effect debuted with "Always".

2011-2012: Debut and solo success
"Lollipop", a commercial single advertising the Plumbob Lollipop phone, was released on September 9th, 2011, as Butterfly Effect's first song. It was a collaboration between Butterfly Effect and Before School. The single was not promoted, but it managed to reach number one on various online charts. "Lollipop" is not considered to be the debut song by K-Sims Entertainment. In January 2012, London Lee stated that Butterfly Effect's debut song would be "for the bad boys as they(Butterfly Effect) swear that they will never be fooled by them again, with straightforward lyrics, a tough rap segment, catchy chorus, fun choreography, and bright colors." "Always" was released on April 23,2012, and was accompanied by an acoustic version. The song also went to number one on various charts and garnered Butterfly Effect their first music station awards on Landgrabb Station. Following "Always" was the release of the group's 1st Full Album, they promoted with the song "I Love You", which would later go on to win various end of the year and music station awards.

The group went on brief hiatus post-promotion of "I Love You", with London Lee revealing that the members would start solo careers. Minchae went on to promote her song "Cherry Coke", Ana promoted "Reason I became a Witch", Nallia released "Dirty", Kiki promoted, "Bloom" and Dohee released "Make Me Ugly Plz". Each of the songs achieved various levels of success, with "Bloom" topping many online charts and winning various awards.

2014: Members leaving and Comeback
After a group’s hiatus on 2013, K-Sims confirmed the departure of Dohee and Kiki and the agency stated that the group will continue as a trio. The group went on to release "Payday", Nallia revealed on her instagram that, ''“Payday” the song is about exactly as the title says. It’s a song about working hard to get payed then going out to party using that pay. Vih and me produced this song with monitoring from Ju.k. Min Chae, Ana and I wrote the lyrics. Xiao provided the choreography for the single with the us styling ourselves."''

Many fans took to boycotting K-Sims Entertainment after Nallia went live on SImtube and revealed that the group basically had to beg to promote again and that the company only let them promote provided they do everything themselves.

2015: Mixtape: F*ck K-Sims
On the girl groups anniversary Nallia went live with Minchae and Ana and revealed that the girls were working on a mixtape together that would be released sometime that year. In the live stream they revealed that K-Sims Entertainment kept promising them a comeback with a mini album but that every time they got close to putting the album together K-Sims would shut it down and make them work on other things instead. They said that Minchae was basically forced to take acting jobs and do OST's, Ana was told to focus on guest appearances and hosting jobs, and Nallia was told to help produce music for other groups. Minchae said that out of all of the girls Nallia was doing the worse because most groups and companies didn't want her music style so she would have to either scrap the songs or lyrics she wrote and would have to start over again. Nallia said that she wasn't making any money compared to the other two girls and that she had to move in with a friend.

During the live stream they talked a lot about what was happening inside the company and with other groups that had debuted, while talking about the issues a fan said that the mixtape should be titled "F*ck Ksims" and that other artists from K-Sims Entertainment should be featured on the mixtape. Nallia said she liked the title name for the mixtape and said she would have to ask people outside of the company to be in the tape because they were already risking their own careers they didn't want to risk others.

On October 31, 2015 the group released their mixtape on soundcloud, the mixtape received love from fans but was met with criticism from some people including people that worked at K-Sims Entertainment. On December 18th, 201 the account that the mixtape was uploaded to was deleted and Minchae made a statement revealing that Nallia opted to delete the account because it was causing more issues then expected with the people involved.

2016: Scandals
On January of 2016, AsianSimsNews reported that Minchae was being investigated for drug use, drug smuggling and prostitution. The article stated that Minchae was working in a "sponsor" program and that someone would set up dates for her with random people and she would go see the people and be payed for her time spent with the dates. It was reported that when set up on some of her dates they were overseas and that sometimes the dates would ask her to take packages back with her and drop them off at a friends place. Minchae said in a statement that she didn't know what was in the packages and that her manager was the one that always had the packages, she also said that she thought she was meeting with fans and stakeholders on behalf of the company. She said she didn't realize anyone was being payed for her going to the "dates".

A few months later in March it was reported that Ana was cheating on her then boyfriend (a non celebrity), with a member of Before School and that she was pregnant with the baby being the ex-boyfriends. Ana went on her Instagram to deny the claims, she showed photos of her and her then boyfriend still together on vacation and revealed that they were actually engaged. But two weeks after her post she revealed that because of all of the hate and rumors being spread around her boyfriend decided he didn't want to be apart of that life and ended their engagement.

In June it was revealed that Minchae was found guilty of prostitution and was fined two million KRW and she was on probation for 2-years as a result of the drug charges against her. The judge in her case said that while it was a first offence for drugs she was still a public figure and had to be held accountable. Minchae deactivated her social accounts the day of the ruling and wasn't seen anywhere public for the rest of the year.

On August 23, 2016 Nallia announced on her Instagram account that she was married and was pregnant, she said that she tried staying quiet on her Instagram since the start of the year because of the scandals but that she was so happy about her being pregnant that she had to share the news with fans. She said that she got married earlier that year and that her baby would be born sometime in 2017.

2017: Nallia gives birth and comeback talks
In July of 2017 Nallia revealed she had given birth months earlier and that she and her husband wanted some time alone with the baby before they announced anything to the world again. She revealed that she gave birth to a baby girl and named her Na Rae. She also revealed that she and her husband had taken in a teen named Mali Bunnag, she said that Mali was from Thailand and that she had moved to be closer to her boyfriend and to be a trainee but her boyfriend had abandoned her leaving her to live on the streets. Nallia and her husband had agreed to take the girl in as long as she worked hard and helped out around the house. Nallia said that she was helping Mali release a mixtape of her own and that it would be released soon.

On September 18, Minchae reactivated her Instagram account and Ana posted that the group was talking about coming back. A few days later Ana posted that the group was going to be coming back in 2018 with a new song and possibly a album.

2018: New member and comeback
On June 7th, K-Sims Entertainment posted a music video teaser revealing the title track for their comeback album as "Fire", in the teaser fans noticed that instead of three members there were four leaving many fans confused. A few hours after the teaser was released K-Sims Entertainment revealed that the group added a new member named Eunah, they said that the group had accepted Eunah as one of them and that they were happy to have her join them. Many fans protested the addition of Eunah but most fans accepted her using Nallia's last minute adding as an example of how sometimes adding someone new can be a good thing.
