Special 2 Years|Yandere X Reader

It's a raining day and you forgot your umbrella. You first ignore it and goes home anyway, but it starts to rain like hell!! So you run to the closest place, that is a patisserie.

You wait for the rain to stop in front of the patisserie. (It was a ceiling outside, you know, the short ceiling outside a resturant or a café)

Suddenly, someone opens the door from the within. It was a boy around my age, with black hair and red eyes.
"Here you go!" The boy say and gives me a umbrella.
"T-Thanks...!" You say, trying to sound nice.

You take the umbrella and goes away, but:

"You're welcome, (Y/N)!" The boy say with the most creepiest damn voice you have ever heard in your life. You just smile at him and goes even faster away.

Who is that boy?
And how does he know my name!?
