You, Bakugo's girlfriend just got home from shopping and saw Bakugo talking with Denki (dunce face to him) and Kirishima (shitty hair to him) on the couch. You had the wonderful idea to see if it would embarrass him if you sat in his lap, even if he hadn't noticed you, yet. After you put your clothes on your bed you went back to check if they had moved or left, they were still there as if they hadn't noticed anything. Then you started walking to Bakugo and just sat in his lap since he usually sat with his legs spread. He just gives a smug look like "yep, this is my girl" "Hey dumbass, how was shopping?" He says while his arms are tightening around your waist. Kirishima is just going "awwww" at the whole situation and Denki looks jealous.
