You aren't exactly friends, but you aren't lovers or strangers either, that's your situation with Yang Jungwon. He's the bestfriend of your sibling, is that the best way to describe your relationship?

"Hi, It's been awhile since we've spoke, right?" He said happily with a smile, closing his locker. You didn't realise it was so close to yours.. "I'll come over sometime this week, be prepared." He said teasingly with a wink, he can't even be normal with his bestfriend's sibling.
