The Hakuba (via meme prompt):

“Were I to find you tied up, blindfolded, and gagged on my bed… I’d likely take the gag off, first, and ask if you’d meant to be there that way. Depending on your answer, I suppose, I’d decide if I were to be naughty – stealing a kiss to start – or nice, and simply setting you loose with an apology and an offer to help catch whatever culprit. And then, if it turned out to be a roleplaying game, well… I suppose I’d rather catch you myself, anyway.”

Was that… Hakuba…?
All Kaito could see was darkness. A cloth-like material was obscuring his vision, firmly tied over his eyes. Tugging on his bonds as he attempted to turn towards where he had heard a voice…
“Mhpppfff! MHak…ku..pff…" 
In a muffled voice, he tried to call out despite the gag. 
Ugh, this is ridiculous. He had found himself in this… predicament since he woke up… having no recollection of how he ended up like this. It was a mystery… and it had been an hour already. Hoping desperately that he was not imagining voices, he tried once again, mumbling incomprehensibly against his gag. 
Release me, damn it.

The detective really could not believe what he was seeing. It really was who he’d thought, bound, gagged, blindfolded… But how? And why? Hakuba glanced toward his windows, which were shut and appeared to be locked as per usual, then turned his attention back to the young man. 

"I’m going to take the gag off of you…” Hakuba warned in advance, putting one knee on the edge of the bed so that he could lean over, and remove said gag, being very careful not to get any of Kaito’s wild hair trapped between the knots. “So that you can tell me what’s going on. And then…”  With the gag removed, he shifted back, just somewhat. 

“And then I’m going to ask you if you’d meant to be here on my bed. Would you like me to remove the blind fold, or is this part of some trick, Kuroba-san? I’m afraid that I only play games where explicit consent is given; you’ll need to speak up if there’s some sort of ploy at work."
