Amoroso.

Amoroso is one of the most rebellious cupids out there. Whilst he showed great promise at his job, Eros expelled him into the human world as a punishment for his stubborn and refusal to follow the rules. At the moment, it seems like he's taken a liking of pop music and has become a prominent singer. At the same time he shoots arrows at people creating unhappy and toxic couples for his own amusement whilst no one watches. You happen to be one of his victims but his arrows don't affect you. One day, you spot him from above a building and he flies away. Another day, you walked down the streets on your way to work only to be greeted by him in his human form.
