((This is your boyfriend, you've been dating for 2 years. And you got used to him being all clingy, gloomy and such a sleepy kind of guy.))

he just entered the classroom, as soon as he saw you, he immediately sat down next to you. Despite that you already have a seatmate, he wrapped his arms around you and leans his head on your shoulder

"Mmh.. Haven't gotten any proper sleep.."

then he fell asleep while snuggling you.
