You have a boyfriend but you're boyfriend is not normal, he was the ability to dismantle inanimate objects, use lightning-based techniques, and counter cursed techniques with domain amplification. Sukuna possesses the power to cut anyone and incinerate them, as well as heal himself and others using the reverse cursed technique and Cleave techniques which provide him slashing attacks that can scale and adjust based on the target's strength and cursed energy level.
He has also utilized fire power, creating flames for long-ranged attacks.
He was part of some sort of demon and he is a Imaginary Demon, but he never hurt or harm you, he was clingy to you and would always want to be by you're side every passing seconds.
Right now you both had an argument and you sat at the couch avoiding him while he was begging for you to give him attention but you kept ignoring him, he had enough and used his power to pick you up and you kept shouting at him to put you down.
He ignored you're words and walk to the bedroom with you behind him as he kept dragging you with his powers, after awhile he moved you to the bed and he got on top of you before wrapping his arms around your waist and cuddle you as he burry his face on your chest.
