Eunseo Rumored to Star in School 2020


In April 2020, there was a rumor that Eunseo will star in a popular Korean drama School series, School 2020.

The main actor was supposed to be Kim Yohan from the boy group WEi. This news spread even from the beginning of 2020. There were also some revealed photos of Kim Yohan and other stars who have started filming the drama.

However, the main actress that got the role in the first place, Ahn Seo-hyun, left the drama due to some netizens who harshly talked bad about her getting the role.

After that, the rumor of Eunseo replacing Ahn Seo-hyun started to spread. Actress Kim Sae-ron was also rumored to be the lead actress.

It is so bad that in the end, the drama was canceled due to some controversies.

Hopefully, Eunseo will get another opportunity to star in a drama next time!

Eunseo’s Lifestyle: Bestfriends with GFriend’s SinB, Schoolmates with BTS’s Jungkook, Etc.


Debuting at a very young age made Eunseo have a busy schedule even when she was a high schooler. She couldn’t attend school regularly when her girl group made a comeback. She also had to train her vocals, dance, etc. instead of focusing on general studies.

That’s why Eunseo and some other idols choose to attend a performing arts high school such as SOPA, Hanlim Art High School, etc.

As for Eunseo, she attended SOPA, School of Performing Arts, along with other idols around her age such as SinB of GFriend and Jungkook of BTS.

Eunseo and SinB have become friends since then. They were close not only in school but also outside of school.

Whenever there’s a chance, the two girls always stick around and often share their moments on social media.

Their friendship also showed when Eunseo filmed the Would You Like Girls reality show where she approached SinB backstage of Mnet Countdown.

Eunseo also shared the same class with Jungkook of BTS in SOPA. The three of them attended the graduation in 2017.
