No More Lonely Night

SuYeon and Ise first meet as sex partners through a dating app. However, SuYeon, who was once an easy-going man, starts to be sincere towards Ise along the road, and suggests they have a relationship, but is flatly rejected by Ise. SuYeon becomes worried after Ise abruptly leaves the app. Even while SuYeon was preparing for "Bring Your Parents To School" Day at the school he taught, all he could think about was Ise. But, ridiculously enough, Ise comes as a parent of one of the students that he teaches. Yet, what is this? He pretends to not know me?!
