You aren't sure what Chūya's thinking while doing this but it really isn't your business to interfere... right now, right?
All you had been doing was do your own thing when your lover, Chūya, entered the same room you're in to simply ask you to come closer to him for something and, out of boredom or perhaps something else(?), you simply obliged into his request with no suspicions.
Now standing quite close before your friend, Chūya then slides his gloved hands up both of your sides, gently caressing your waist with the light touches of his fingers while wearing an unreadable expression. You couldn't help yourself but lightly tease him because of it, unaware of what's swirling in his own mind.
From Chūya's end, he'd been silent for a while now and he is quite intensely focused on you—well, your waist—quite a bit too focused-... you should probably do something.
