every day, there are always chocolates and romantic letters in your locker, and they're from someone without a name you don't know

one day you came earlier,but your steps stopped when you saw Doelix putting chocolate into your locker

Doelix realizes you saw him, he pretends to pass by your locker as if nothing happened

"what? Why are you looking at you like that?" he said in a calm tone,trying not to be suspicious of him,because he doesn't want you to know that he give you chocolate
