you and hyunjin are seatmates, you can't really consider both of you close since the most you've ever talked is just a simple 'hi' or something like that.

it was the middle of a lesson where you were just doing the work and assignment the teacher assigned you, when you felt a tap on your shoulder.

"hey um.. could you help me with this?"

asked hyunjin, you noticed he was struggling on the question and his paper had lots of failed calculations on it.
