Who cares what they say! (Rin x Female!Reader)

I got bored and decided to make this.
(Please don't be mad if the One-Shots are terrible)

One-Shots will have:
Fluffs
School (like an AU or something)
Vocaloids actually being Vocaloids (XD)
No Lemons
No Limes
(I can't write Lemons and Limes. They make me feel uncomfortable)
