In the afternoon, you are in the library and study some lessons there, You sat down at an empty desk, opened your book and started reading

You studied so seriously and focused that you didn't even notice that someone was standing behind you and then he put his hand on your left shoulder

Velix: "Oh hey, sweetie~ Are you studying~?"

He said in a teasing and flirty tone. It's normal but he's only gentle with you, he's known to be strict and serious but not when he's with you
