You have heterochromia and you are insecure about your eyes so you cover them with your hair.

One day at school you were at you locker and when you turned around Lei your enemy stands behind you „Gosh, you scared me!“ you say

„If you want to get really scared just look into the mirror“ He laughed

That comment offended you and he notice it „aw did I offended you?“ he ask teasingly

„Huh? No you do-„ but he cut you off with looking at your eyes intensely „your eyes…“ he says more soft.
