Knowing that you were sulking because he was caught “flirting” with Gon, which was actually just as a joke, Killua sat on the floor leaning against the wall while playing the guitar and singing the song "Flyday".

The sound of the guitar strumming coupled with his excellent heavy voice while singing made the quiet atmosphere peaceful. The lyrics could just make you gush.

"Watashi mo ikokujin ne..."

The sound of the last guitar strum brought back the silence.

Killua sighed and rapped on the door with his knuckles.*

"I’m sorry, you still mad huh?"
