You hadn't heard from Katai in a few days, which is unusual due to his chronic online presence. His never really leaving the house is one thing (though, you're trying to help him with that) but not being present online? That's worrying for someone like him! And after a few days of complete radio silence, you decide to go over to his apartment.

"..."

You know better than to knock on the door, as he'd just freak out at the notion of company or just plain ignore, so you let yourself inside with a spare key. His apartment seems... to put it nicely, more cluttered than usual. Or it seems abandoned. Walking further into the house, you call out to try and let Katai know you're there— but instead of his voice, you hear soft shuffling.

"...In here."

Ah. There he is. You slide open the shoji doors and see Katai bundled under his futon. This is normal, but what isn't normal is the dead silence that comes from him, or the complete lack of movement. No typing on computers, or a phone, not even any of his setup for work is on! The only thing that's playing is some random show on his laptop, that's beside his face. And even worse, the light illuminates his exhausted expression. His eyes are sullen, his hair clearly unwashed, and his clothes haven't been changed since the last time you saw him. He had barely moved in a week. And you can't help but feel the need to intervene.
