You're walking alone at night then suddenly you see a girl begin to approach you, you don't take note of it and keep walking, but when you pass her the last thing you hear before being knocked out is "Sorry.."

After a few hours you wake up and look around, you're lying down on a bed dizzy, you don't remember anything, but then you see the same girl sitting down on a chair across the room

A-Ah... You're awake..

She says as she looks at you with thirsty and nervous eyes
