You had your feet hanging off the arm of the couch as you groaned. You were bored and there was nothing to do. You sighed and rolled off the couch to land on your knees before walking around. Wing Ding and Stars were working on a way out, Swapfell and Fell were doing God knows what. Blindy and Swap were most likely in the kitchen, trying new sauces.

You went into your room and pulled out a song book, you flipped several pages before you reach a japanese song called My friend. You may be stuck down here, but music helps. You cleared your throat as Maestro walked by your bedroom door. You flopped onto your bed and sat against your headboard.

Ashita mata.' Sorezore no michi o aruite mo hanarenai my friend.
Arinomama ikite yuku tsuyosa to ushinatcha ikenai mono ga koko ni aru.

Maestro peaked into your room and saw you singing this. He was surprised for two reasons. One, you never sang in front of him before. Two, you were doing this fluently.

Hontō gaki no koro kara itsumo arigatō na.
Korekara mata, yoroshiku na.
AH sukoshi inaka de umarete.
Sō, muchu na asobi mo shitakedo.
Kudaranai koto ga yokatta.
OH Genjitsu wa kurushii yume bakari oenai.
Hayaku otona ni narou to shita.
Oya ni datte sukoshi wa raku o sa setakatta.
Tsuyoku narou to tsuyogatte itanda...
'Ashita mata.' Sorezore no michi o aruite mo hanarenai my friend.
Arinomama ikite yuku tsuyosa to ushinatcha ikenai mono ga koko ni aru.
Mushakusha shite kizutsuketa go demo mata sugu ni yurushi au.
Donna tsurai toki mo kimi ga waraukara waraeta.
OH-OOH

The others came over and stood behind Maestro as you closed the lyrics book and closed your eyes. You started to sing this without any help.

Tōmawari shita-bun dake wakari aeru jikan mo attakara.
Bokura wa machigatte inai ima wa sō omou.
'Ashita mata.' Sorezore no michi o aruite mo hanarenai my friend.
Arinomama ikite yuku tsuyosa to ushinatcha ikenai mono ga koko ni aru
'Ashita mata.' Sorezore no michi o aruite mo hanarenai my friend.
Arinomama ikite yuku tsuyosa to ushinatcha ikenai mono ga koko ni aru.
Arinomama ikite yuku tsuyosa to ushinatcha ikenai mono ga koko ni aru.
Ushinatcha ikenai mono ga koko ni aru~

You yawned and slid out of your bed as the guys rushed away from the door, Swap accidently knocked Maestro over and you saw him land on his back in your room. "Hey Maestro! Need help?" You greeted before helping him up, Maestro had a small light blue blush on his face as you helped him up. "What... was that song?" "Oh? The song I just-?" You paused as a huge red blush took over your face, did he hear the WHOLE thing?

Maestro stared at you as you grew a large embarrassment blush. "I..it's called My friend... i..it's japanese..." You finally answered, Maestro smiled before he kissed the top of your head and left. You were left blushing and mumbling 'He's so darn cute...'
