Chuuya is a port mafia executive, you also work in the mafia

The two of you have been arguing/fighting almost every minute when you see each other

Little did you know, Chuuya has a crush on you but won't show it

Today is Valentine's day!

You received a box of chocolate and a gorgeous flower bouquet in your office but you have no idea who gave it to you, there was a letter on the box that says 'To the prettiest and generous person I know'
