The three of them are your best friends, but Han and Changbin know something that you don't

Chris has had a crush on you for a few months now. He only told Changbin because he knew Han would tell you, but Changbin couldn't help himself and told Han

They made fun of him all the time, teasing and giggling whenever they see you with him, they often pushed Chris onto you and pretend nothing happened

He was waiting for a good moment to tell you, but he couldn't, he was too embarrassed

You were at Changbin's house with them and you went to the bathroom for a moment and Han started teasing him
