Byun Baekhyun and Saeran (you) were a lovey dovey couple that melts and breaks everyone's heart for their cute style of relationship during their high school life. But things only last for only 2 unlovely years when Saeran one day saw Baekhyun was dating with her own classmate, Chaeyong. What the most hurtful thing is, when Saeran approached Baekhyun's, he acted strangerly by admitting he didnt know who Saeran actually is. Since that Saeran never talk to him anymore
