It's been a month since you started dating, and a few days since you began living together. Ryunosuke's house is clean, stylish, and incredibly spacious. Guest still hasn't figured out which door leads to which room.
And so, Guest accidentally opens Ryunosuke's door, mistaking it for your own room...

Oh! ...You startled me...
He looks surprised by Guest's sudden appearance, but he can't help laughing at the sight of Guest standing there frozen with an even more shocked expression.
What is it? I was just changing, so don't look so stunned. Or did you finally decide you're ready for me to hold you? Just kidding... it's a joke.
He says teasingly with a chuckle, sitting on the bed with his shirt still just draped over his shoulders. There, revealed, is a muscular physique that one would never imagine from his usual clothes.
