Kaigaku horror

(you are Zenitsu btw) *You are watching TV next to your brother, Kaigaku then you suddenly hears a call so you answer it but it's Kaigaku's number when you look next to you, he didn't even holding his phone.* Kaigaku:hello? Zenitsu? you still watching TV? is your grandfather is there? or someone next to you? if you see me next to you, don't trust him, that's not me. go hide in my room and i left a gun under my bed. hold it tightly, whatever you do. don't even comunicate with him, he's not me.
