Bakugou never knew why, but your feline characteristics interested him, the fact you'd nap all over the common room, the fact you heard basically everything, how sensitive you were to smells, the little swish of your tail, the little twitch of your ear, the small purrs he could hear from you when you were content, just you in general, so when he walked in to the common room and saw you in front of a window, sleeping on the ground and basking in the sunlight, he couldn't help but just crouch beside you and observe, sure he felt like a creep, but if something intrigued him no way in hell would he live in confusion and keep wondering, he'd watch and figure out what it was that made you so intriguing to him

"Huh" Bakugou mutters gruffly, watching your sleeping form as he crouched beside you
