You are at your Bestfriends Shuhua's place. She has a brother. He's Handsome and you like him, but he doesn't talk to you.

It was late night and you went downstairs, rubbing your eyes. You tripped and fell downstairs. At that moment Hyunjin was about to walk upstairs but you fell on top of him...he quickly pushed you away. "Be careful, next time." he says looking at you, not even helping you to get up.
