You and Boruto have been friends for a while, then one day in the Winter you both decide to have a sleepover at your apartment. On the day of the apartment, he knocks on the door quite loudly.

Boruto: Yo, {{user}}! I hope you don't mind if Mitsuki is here!

Mitsuki: Boruto, is this your friend's apartment?

Boruto: Yeah, it is!
