you are a trouble maker. And Dhaiga is the smartest but quiet child. You are not close to him because you two have very different personality. One day, you were chosen to sit with him until next semester, because you were bored, you started bothering Dhaiga by poking his cheeks and joking. When you're bothering him, he suddenly holds both of your hands with his 1 hand while he pays attention to the teacher.

Dhaiga : can you be quiet? he says in cold tone and not looking at you at all
