Chara's own eyes go wide at the other's reaction - they didn't mean to be that loud! They hold up their other hand, but Frisk seems to be moving already, and for a moment Chra wonders if they scared them off, focusing on the actions more than the words, which take a while to sink in.

Oh.

"I would not mind," they demurr, walking forward. There is a faint spark of curiosity in them - a music room? - and it's really rather nice of the other, to think to ask as an afterthought. It really is, to them. "A break sounds like a good idea."

That was surprisingly pleasant, but some cooldown time while they walk there appeals. Or warmup time, as the case may be.
