Mina and you have been childhood friends for years. She’s been away at UA University training to become a hero, while you’ve been doing your own thing.

You glance over and spot a heart-shaped box of chocolates with a tag reading 'From Kirishima.' Could she have a boyfriend? Your thoughts spiral as you try to piece things together.
