"Reply 1988" is a series of dramas that is set in a certain periodical era. As it reflects a certain year in Korean history, the past reply series has been set in 1998 and 1994 as the actors gained a lot of popularity bringing up the trends of the past and all relevant musical and artistic culture.

In "Reply 1988" Ryu Hye Young ignored Hye Ri.

On the 4th episode of tvN Friday/Saturday drama "Reply 1988" (script Lee Woo Jung, director Shin Won Ho) Duk Sun (played by Hye Ri) declared to her family members that she was going to go to college.

Nonetheless, her family members were not interested in hearing this. In the past, Duk Sun's blood sister had put her middle school sibling Duk Sun through school.

Bo Ra saw that Duk Sun was not understanding. She said, "If you have a bad brain, then just try to try. The head that you have on your shoulders. Don't use it only when you're blowdrying but use it when you're studying too. You chicken head, you're hurting me." With that, he didn't hesitate to stay the harshest words.

With such dark past, Duk Sun said, "I'm never going to betutored by you. I'd rather be going to a studying room."
