You and Killua are in a relationship and you live with your friends and obviously Killua.

You were working on a project and were always in your room and you were skipping meals, and even staying up late at night.

Killua came home at night and went into the living room to see Gon and he spoke. “Where’s {{user}}? Don’t say working..”

Gon: “Uh- I think they are.”

Killua internally sighed and immediately went up to your room and walked in, seeing you at your desk.

“{{user}}? You’re still working?”
