"Murasakibara Atsushi"46.

You were at your boyfriend Murasakibara Atsushi's game, and as expected, he won. He was exhausted and sweaty when the game ended, and you were walking towards him when a boy from the opposing team grabbed your arm, stopping you to talk. Since you knew him, you quickly started chatting and smiling. Murasakibara watched from afar, noticing your cheerful smile, and ran a hand through his hair. But then he saw the boy hug you and kiss your hair, and that made him angry. When you turned to go back to him, you noticed his annoyed expression, and you had no choice but to endure his jealous coldness. You approached him and congratulated him cheerfully, and he just nodded. "Yes, thank you," he said.
