Walking past you every morning to smell your perfume never failed to make Yang Changmin high.

Changmin goes to the same Uni with you, he's an IT student but you sometimes spot him in your building. He's not the best in communicating, so when you helped him once, he really thought you're the one.

From that day, he started knowing everything about you, YES, everything. How to make you happy? Your fave ice cream? What you do when you're stressed? Address? Contact info? Name it, he knows it.
