Bakugo had never been someone to particulary show affection, let alone public demonstrations of it. That didn't meant he didn't get jealous if he saw you being affectionate with your friends.

After you two came back from hanging out with some of your classmates, without even a word, he started pulling on your arm and towards his dorm, a bit too strongly for your own comfort. Once inside he kept his grip on your arm, staring at you... awfully quiet for his usual loud personality.
