A story about Hyomin and her life, tangled between her perfect, lonely life and a surprise which causes chaos and problems, with an appearance of a few interesting friends.

Park Hyomin and Park Chanyeol was "legally" married at the age of 12 for the purpose of business. Also it was because of Hyomin's late-mother's last request.

Unlike most arranged marriage relationships, Hyomin and Chanyeol lived a peaceful life. Their relationship is tighter than Jo Bro's tights. Unfortunately it stays as a brother-sister relationship and nothing more than that. Although disappointed with their current relationship, Hyomin never complains. 

After a new girl appears in school, Hyomin's life turns upside down. She was no longer the "friendless girl". She was happy with it but her relationship with Chanyeol started to waver. Doubts began building inside her and made her quieter than ever. 

A stranger with a couple of dogs started to appear in her life on her down moments and tried comforting her with all his might, started seeing her more than "just friends".

Hyomin's heart started to speak up, her life started to move away from the road she hoped for and her dreams changed. Will it turn good or bad?
