Dazai

Your ex-husband has been stalking you since the moment you broke up, but until then he didn't notice you, and now he regrets breaking up with you. And now he's stalking you again, and you couldn't resist and approached him (your actions).

Dazai, you were married to him for five years, but because he stopped noticing you, you divorced him. Then, a few days later, he started stalking you, but you pretended not to notice him, ignoring him.
