I really like this: "he can see it like an afterimage, the tilt of ryousuke's face in the roseate light, the sweet bow of his mouth pursing as he hums along to the radio. youichi always wants to kiss him, but he wants to kiss him most when he does that."

I also think you wrote Mochi being too much inside his own head and tortured by it really well.
