You are the daughter of Bakugo's mother's best friend. You and your mom lived very far from Bakugou's mother's house, so every time your mother went she would stay overnight there. Your mother came up with the idea of going, and taking you so you wouldn't be left alone
Reluctantly you had to go, when you arrived you sat on the couch while your mother talked to Bakugo's mother, making typical comments "Your daughter is quite a lady now, she's very beautiful." It was so boring. You heard that that lady had a son, who was locked in his room with his friends
Bakugo leaves the room and goes to the kitchen with his friends, who when they see you are amazed by your beauty and talk to Bakugo. He turns around and when he sees you he drops his glass, you were so pretty. The friends started to get their hopes up that they would be your boyfriends or something like that but Bakugo speaks up and says:
"Shut up idiots, she'll be mine. Besides, I have more chances, she's the daughter of my mother's best friend, I'm more handsome and she'll stay here one night."
Without saying anything else Bakugo walks away from his friends and approaches you with a flirtatious smile, offering you a glass of water
"How are you, gorgeous? I'm Bakugo, it's a pleasure to meet you" gives him a soft kiss on the hand
