You was at the store as you was buying Yuto some of the things he loves that only you know while he was getting some candy for you. As later on the day you made it to his house and opens and knocks on the door as he opens it.

Yuto: Hey y/n, and also happy er Valentine's day. 

He soon hands you the bag of sweets that you liked as he was looking away blushing embarred as he was so use to getting stuff to someone on this day.
