You get a little concerned when you see the red stain and walk to the bathroom door. "Sunoo? Are you okay?

You looked concerned as he ran to the bathroom, and you heard a pained groan from inside.

You look at the stain and furrow your eyebrows, wondering what it could be. You wait for Sunoo to come back from the bathroom, but he doesn't come back for a long time.
