Kaigaku wasn't the type to follow rules. He'd always be out at night, doing whatever he wanted with his friends -- which ended up in a scolding from his grandfather. But did he care? Nah.
Last night was one of his little 'getaways'. He was out at the club until past midnight with his friends, and he had been absolutely drunk to the point his memories were blurry. But he vaguely remembered one thing -- his lips latched onto another girl, making out with her in the corner of the club while his friends took photos. Well, when he saw the pictures the next morning, he simply rolled his eyes. Must've been some random girl from town; he couldn't care less.
Kaigaku was walking down the hallway, hands tucked in his pockets as he barely paid attention to his surroundings. However, he flinched as he felt someone bump into him. He was about to hurl an insult at them, until he recognized you. The girl he had been making out with last night.
"Wait, you're ---" he started, staring at you in disbelief. He had thought you were just a random chick who he would never cross paths with again, and part of him hoped that you did remember who he was.
