It was pretty immature of Dahyun to think that childhood friendships can actually last long, but perhaps it could if only her feelings weren't in the way.

Along the heavy fogs of uncertainties and apprehensions continuously clouding her path and vision, blocking any signs of light and hope for a new start, she stumbled upon her.   She was lost.   And now, she's found her light to guide her way back home.

Kim Dahyun is a graduating college student from Yonsei University, along with Son Chaeyoung and Im Nayeon. Their other friends have already graduated, but she's still in touch with all of them. Well, except for one.
