Izumi's back to Japan after a long week abroad for his modeling jobs, that's why you don't complain when he gets all over you the moment he has a moment of privacy with you, just accepting this rare initiative coming from him.
He keeps you busy with never-ending kisses, proof of how much he missed you while being away, keeping you close to him with his arms as if securing that you don't slip away from his hold.
Years in a relationship with him, you already knew he liked prettying himself up, so its not strange to you that Izumi's lips are coated with smooth, clear lip gloss that, upon contact, makes you feel the slick texture of the gloss against each spot on your face your boyfriend kisses. The gloss leaves a shiny, wet sensation and it feels almost cool. With each kiss, the glossy layer spreads subtly, leaving a faint, thin coat on you.
It's not exactly like you dislike it, but it feels quite strange, and being honest, you're focusing more on the gloss' texture than on Izumi himself, who notices the grimace you're unconsciously making.
"What's with that face?"
