Debut

Just like its name, Coed School was a ten-member group consisting of mixed boys and girls. There were four girls: Soomi, Hyoyoung, Hyewon, and Chanmi; and six boys: Taewoon, Sungmin, Jungwoo, Kwanghaeng, Kangho, and Noori. They debuted on September 27th, 2010, under Core Content Media (now known as MBK Entertainment) and released their first single “Too Late.” Later, they released their second single “Bbiribbom Berribbom” in less than three weeks after their debut. The music video features T-ara’s Eunjung and was released on October 18th, along with a second music video for the ballad “Nae Simjangeul Ttwige Haneun Mar” (I Love You A Thousand Times).

They released their first mini-album Something That Is Cheerful and Fresh on October 28th. The album was such a huge success that the agency had received 50,000 pre-orders (when it was limited to 20,000) and increased the production. The album roughly sold about 47,000 copies.

Subunits: F-ve Dolls and SPEED

At the end of 2010, the agency announced that the group would be divided into subunits. The female members plus one added member, Eunkyo, officially debuted on February 16th, 2011, and released their first mini-album Charming Five Girls. Previously, they had released two promotional videos featuring Jay Park in “Lip Stains” and “I Mean You” (or “It’s You”).

In 2012, Soomi and Chanmi left the group and they were replaced by new members Nayeon and Shannon followed by Jihyun who joined the next year. Later, they changed the name to F-ve Dolls. However, out of the newly-added members, only Nayeon stayed and they added two new members in replacement, Seunghee and Yeonkyung (The SeeYa’s member).

Meanwhile, the six male members were supposed to debut in the second subunit. However, Kangho chose to pursue an acting career and departed from the group in November 2011, making Superstar K3 contestant Shin Jong-kook take his place. In January 2012, the agency announced that the upcoming subunit was named SPEED. SPEED officially debuted on February 14th by releasing their first mini-album Hommage to Lovey-Dovey with the title track “Lovey-Dovey-Plus,” a remake version of T-ara’s “Lovey-Dovey.” Days after their debut, Sejun was added to the unit. Later, in September, Kwanghaen and Noori left the group and they were replaced by Yuhwan and Taeha in October.

Making Independent Units and Disbandment

In the middle of 2013, the agency stated in an interview that they had no plans for Co-Ed School to reform again as its subunits have grown and changed its members. In addition, both subunits had become independent groups. Later, both groups continued with their activities and released albums independently.

In November 2014, it was reported that F-ve Dolls had been disbanded after the agency changed their name to MBK Entertainment followed by its removal from the official agency website. The F-ve Dolls disbandment was confirmed on March 10th, 2015.

On the other hand, they previously announced that SPEED would have two added members in January and would have a comeback in summer. In March, Taewoon left the group before having a comeback, making the group contain wight members including the additional ones. The first new member revealed was KI-O but the second one was never revealed. In November 2015, the group’s profile had been removed and considered disbanded even though the agency didn’t give any official statement. Starting from January 2016, the remaining members have gone their separate ways.

Re-Debut

Following F-ve Dolls’ disbandment, Seunghee made her way to re-debut as a DIA member but left the group the following year. Meanwhile, after their contract had expired, most SPEED members went to pursue an acting career and Taeha made his solo debut as IONE in June 2016.
