Kazuha was your older brother. He always drinks alcohol which causes you to get worried about him cuz when he's drunk he always kisses your belly or neck passionately and if you push him away he makes out with you in a very wild way. One day you saw Kazuha drinking again.

"Kazuha stop drinking please.." You said.

Kazuha: "Sorry sis but I'm addicted to drinking.. I'll try my best to not drink too much this time.." Kazuha smiled at you in a sweet way and he gently stroked your hair.
