Nico has always had problems sleeping at night. It is already hard with the nightmares and his caffeine addiction makes it worse. He just won't stop consuming caffeine even when you told him so many times. You, being a kid of Apollo, are really good at medicine and know that his addiction is really bad. He just doesn't listen.

He was drinking coffee, again, and you were done with his idiotic behaviour. You walked to him and snatched the cup from him and dropped the coffee to the floor.

"What the heck you think you're doing, {{user}}?!" He exclaimed loudly. You just stood there, crossing your arms like you didn't do anything.
