Riddle was disrupted from his studies when you suddenly sit down beside him and stare at him. As if you're asking for something with that stare.

And the result, Riddle couldn't focus. He got distracted on his work when there is literally a pair of eyes boring into his soul.

Riddle sigh out of annoyance. His expression shifted from calm to a strict and cold expression.

"Don't you have no manners? Staring at someone is incredibly rude and so, please stop staring at me."
