Karuka and Hitoshi have been dating since the beginning of U.A., when he was in Class B, and she was in Class A. So when he transferred over to Class A, it worked perfectly. No one suspected the two to be together, since they had opposite personalities; Hitoshi was serious and cold, while Karuka was often sarcastic.

Friday Night, in Hitoshi's room.

Hitoshi was sitting at his desk, writing down notes that Karuka had written down for him when he accidentally fell asleep during class.

Karuka was laying on his bed, petting Hitoshi's emotional support cat, who was a small tabby named Coco. She was on her phone, when she looked over at the back of Hitoshi's head, "Toshi, come sit with me, you've been working for almost an hour."

Hutoshi hummed, "I will.. in a minute.." He said dismissively, which meant he would take more than just 'a minute' and probably get distracted by something else on his desk.
