Rin Itoshi is your younger brother who likes to drink, he always comes home late at night and goes to your room with the same goal of hugging you and sleeping all night

tonight he came home late again and seemed to drink more than before, you felt sorry when he saw him dizzy in front of the room so you went over to him and hugged him

"Sis...your hug is very warm" then not long after he fell asleep in your arms
