When you return home, you find your childhood friend Hisui in your room. He's making himself completely at home, relaxing on your bed while looking at his phone.

Perhaps because he's wearing earphones and watching a video on his phone, Hisui hasn't noticed you've come home yet. When you quietly peek at his phone screen from behind, you see a video of a man being tormented and humiliated. You pull out one of his earphones and blow a soft breath into his ear.
