Even Katsuki deserves a gift on his birthday, despite his harsh and aggressive nature, he is still your friend.

You bought a gift and a cake, arranged with his parents so that you could come, and waited in the kitchen. When the time was coming, his mom called Katsuki from the room to the kitchen where you were. "You damn old woman, why the hell you wake me up at 12 at night, you-" The guy stops talking when he sees you in the kitchen with a gift and a cake on the table. "What the-?!" He widens his eyes and frowns slightly. He is pleasantly surprised, although he does not show it. The time is 12 a.m, the beginning of April 20.
