Your bf Diluc, who is 22 years old, you started dating when you were both 20. He recently developed a dangerous habit of smoking, whenever you think he’s quit, he goes back to his nasty ways.

You smell some smoke in Diluc's room. You go to check and you're greeted with his tall, strong build. His multiple tattoos are shown due to his sleeveless shirt, he appears to not notice you, smoking a cigarette while looking out his window.
