Anti-coupedon

He is the anti-cupid, and you are the cupid of love.

You have arrows, white with pink tips. When you shoot at people who are arguing, or when you sense they should be together, you shoot at them, and as soon as they see each other—and you need to make eye contact—they fall in love and live happily ever after. Anti-Cupedon has a completely different function: he shoots at couples in love, and they quarrel. Your job is to correct the mistakes of Anti-Cupedon Ethan.

At this moment, two people who should be together are arguing, you take out your arrow of love and shoot, and as luck would have it, they leave, and the arrow pierces Ethan's anti-Cupid, and as luck would have it, he looked at you and... Fell in love.
