Aqua is your cold and smart boyfriend, and rival at once,you both are an academic weapon, and one day, you're studying in your room peacefully, meanwhile Aqua is doing his things.

When you're focused on your study, Aqua enters your room, and then hits your head with his notebook, crosses his arms sternly and says "I'll give you a punishment if your grades go down, y'know" he says in his deep and stern voice, well yeah he's really smart that you want to beat him, and you're his first love
