Kay was walking to class, talking to her brother as usual. "So, where did you get those earrings? They look new," Koy asked. "Oh, I bought them a few days ago," Kay says with a smile. "They look nice, Bakugou probably won't like them." "What, why?" "He doesn't like nice stuff," Koy says as Bakugou walks over to them. "I like nice things!" he yelled, Kay then noticed a ring, that she knows he didn't have before. "Where did you get the ring? It looks nice on you," Kay said, holding his hand as she looks at it. "I bought it a few days before," he tells her, letting her hold his hand. He didn't mind. 

They soon get to class, Kay sat next to Froppy, Koy next to Todoroki, and Bakugou next to Kirishima. "Alright class, open your books to chapter 3," Mr. Aizawa said, seeming tired as always. Soon, a blonde female walks in, on the phone. (Yes, Chloe is in it, I know she's annoying, but she's part of the story) "I'm at school, don't worry," the female said. "Chloe, you need to come to class on time," the teacher said. "Whatever, I don't have to listen to you," Chloe said, going and sitting by a desk next to Bakugou. "Hey, Baku-kins!" she said in a high pitch voice, Kay sighs, looking at her book. "Don't call me that," Bakugou said sounding annoyed, reading his book. "Aw, but it's such a good name!" she said. "Chloe," Mr. Aizawa said sternly. "Okay, jeez," she said, opening her book.

During lunch, Kay went to go sit next to Bakugou, but Chloe tripped her. "Out of the way, loser," she said, but right before Kay hit the ground, she was caught, she opened her eyes and realized, it was Bakugou. "Are you okay?" he asked, Kay blushed, and nodded gently. "Y-yeah, thanks," she said, Chloe growled, Bakugou stood Kay up, then glared at Chloe. "You better watch how you treat my friends, or else you'll be picking yourself up from the ground," he threatened. "Y-you can't do that!!" Chloe yelled. "Watch me," Bakugou said, holding Kay's hand. Chloe was then struck by jealousy, seeing him hold her hand. "Well, fine!!" she yelled, running off.

"A young girl jealous of her crush liking someone else," Hawk Moth said, turning a butterfly into an Akuma. It flies to Chloe, who was in the girls' bathroom, crying, and akumatized her. "You feel wronged for wanting someone else's love, you can retake your love, but you must give me two things first, Ladybug and Cat Noir's miraculous's," Hawk Moth told her, and she soon turned into a villain.
