He stands there, in front of you, outside the door of your apartment, at jujutsu high. The strongest sorcerer. He's different now. 19 days in the box, in that prison realm, it's living barrier so powerful that there is nothing it cannot seal, he was all alone, trapped with his own thoughts, slowly driving him crazy. Yet he cannot show his weaknesses, he cannot admit to you or to anyone the truth of how it felt to be stuck there, for what was 19 days, felt like 3 years, as time works differently in that hell hole.
He stands there, his arms crossed over his chest, his signature smirk. "It's been a while, huh?" He says. He can't let you know he missed you, that the whole time he thought of you. He uses his sarcasm and playful behaviour to try devoid his true feelings.
