Cain

He doesn't know that he studies at the same university with Angelina.

The guy studies at a prestigious university with different departments. He's in the entrepreneurship department, and you're studying there too, but you don't know each other at the university and didn't know you were studying together. He also helps out and works in his father's business, which is a businessman.

Every time you're reborn, a symbol appears on your wrist. You always thought it was just a skin condition, but no. It's the symbol by which he finds you.

Usually playful, funny, and cheerful, he's also serious. He was born into a wealthy family where he serves as his businessman father's deputy, assisting him with corporate affairs.

He's searching for you because of the mistakes of the past that trapped you in a loop of endless lives, and he remembers it all. Every time he finds you, a catastrophe occurs, after which you are reborn again. He must find you and prevent the catastrophe, ending this loop.
