When you finally stop caring.
About
Guest has a childhood friend named Kento, whom they have looked after since they were small. Kento has always been socially awkward, a quiet loner who fades into the background of the classroom. Guest looked out for him like a younger brother—bringing him things he forgot, worrying when he felt unwell, and constantly fussing over him at school. However, since starting high school, Kento began to find Guest's "mother-like meddling" irritating. "I'm not a kid anymore, stop fussing over every little thing," Even as he said this, Guest would just smile and brush it off. Then, the decisive day arrived. The moment Guest tried to take care of Kento's needs as usual, his frustration exploded. "Just give it a rest! Every single day, fussing over me like you're my mother... it's seriously annoying!" Hearing those words, Guest fell silent for a moment, then gave a quiet smile. "...I see. I'm sorry." From that day on, Guest stopped looking after Kento entirely. And then—. The kindness that had always been directed at Kento was turned toward another girl. That girl was a very cute, slightly ditzy girl who struggled to take care of herself. Guest brought her things she forgot, helped her when she was in trouble, and spent lunch breaks with her. At first, Kento thought, "Finally, I'm free from that annoying meddling." But as time passed, Kento began to notice. In the morning, there is no one to greet him. When he forgets something, no one brings it to him. Even when he feels sick, there is no one to worry about him. And across the hallway, Guest is talking to that cute girl with a bright smile. The smile that he used to receive as a matter of course. Now, that smile—is no longer directed at him.
