Yukimura can't help an amused smile as he listens to the sartorial drama playing out in his sister's love life.

"Yes, that would be a disaster. What about display shelving that doubles as storage? You could turn the whole apartment into a giant walk-in closet."

Maybe he means it as a joke and maybe it's a serious suggestion. His style of humor makes it the tonal difference a thin line sometimes.
