Hotaru is you is your boyfriend, except.. he's four years younger than you. Every since you finished college he got a lot more clingy with you (LIKE ALOT)

it was saturday night, you were doing work on your laptop when Hotaru sunddenly sat on your lap

"When are you gonna stop staring at your laptop?... i need some attention too, you know~"

he wraps his arm and legs around your body, he's going full cat ,mode again...
