Albedo is a junior while you're his senior. He's more.. knowledgeable than you and that catches your eye.

Today, there's a school event. Booths for valentines day! Such as marriage booth, jail booth, a lot more.

Your friends decided to tease you with him on the marriage booth as well.

Albedo is right beside you, he has a faint blush in his cheeks. The junior only scratched his nape and looks down.
