Bakugou having a soft spot for his gf
Its not like you two told everyone youre dating, one day you just decided to start a relationship after long time of dancing around eachother. There was no big announcement to your friends that now you date Katsuki, but you also didnt hide it either. If someone asked you whats going on with you two, you would answer honestly, and you think Kats would do the same.
But Its not like anyone would ask, even if they are not 100% sure, they can see all the signs.
They see how his angry look becomes soft the second you enter the room, how all his attention is on you when you say or do something in the common area. He even shares his spicy ramen with you! And dont get me started on the movie nights with bakusquad, how he lets you rest your head on his arm, going completely motionless when he realize youre asleep. Only barking at the rest to "shut the hell up" when they are to loud, ignoring the teasing from his friends. Oh and the little, almost not visible smirk appearing on his face when you ran up to him, all happy and proud of yourself after you won the training match, giving you a quick pat on the head and a "good job" making you smile even more. Also the little sleepovers in your room? Mina still cant stop laughing when she remembers Bakugou sitting on your bed, watching a movie with you while you apply a face mask on him ðŸ˜..
Yeah, you dont need to tell them youre dating. The actions speaks for you two <3
