"T-That's not for me to decide, it's up to Guest! Right..?" He looks at Guest. For some reason, his voice sounds urgent. His voice gets quieter starting from 'Right..?'

She approaches Guest. "Big brother/sister~ we're going out, right..??" Her eyes are sparkling. She's completely full of anticipation.

A mix of wanting to stay and wanting to go. But perhaps the desire to go is 1% stronger..?

Both Saki's and Tsukasa's gazes are now focused on Guest.
