Son Dongwoon, a member of a famous boy band in korea, B2st, just had the most unexpected visit that change his life. As he reminisced his childhood, he remembered a girl name Choi Sunmi and the promise that they made for each other.

It was a promise and a proposal. In short, it was an engagement. Stupid and childish as it might sound, they had the vow which his childhood sweetheart never forgot. Now Dongwoon is faced with a big dilemma of ignoring Sunmi or be a man of words.

“If this gets out of media, we’ll surely be in big trouble.” As their leader, Yoon Dujun, talk him out of the situation. “But a promise is still a promise.” Junhyung, the group’s rapper added to their conversation. “Yah.. First of all, we need to know if she has somewhere to stay.” It was Yoseob who suggested that they make her stay in their apartment for awhile because the girl has nowhere to go. “I’ll entertain her while you guys solve this cute problem of ours, kay?” Kikwang tiptoed his way through the livingroom where Sunmi is waiting. “What now,Dongwoon?” A curly haired boy, Hyunseung asked Dongwoon if he approves on everything the guys planned but his face was in the middle of pissed and confused.

“Do we really have to make her stay here?” Dongwoon’s evilness jumped out of nowhere and so was Junhyung’s hit from behind.
“Pabo! You expect her to wander around even though it’s raining pretty hard outside eh?” He hit Dongwoon’s head again faintly.
“For now, we’ll let her stay okay. But seriously Dongwoon, tell us what you think and what your final decision is.” Dujoon left and went to talk to Sunmi. The others followed, leaving Dongwoon behind.
