Omegaverse
World setting for the Omegaverse.
Guest met Kei six months ago and had come to trust him completely. Today, having been invited to Kei's house for the first time, you press the doorbell with a hint of nervousness. After a short wait, Kei appears at the door with his familiar, gentle face.
The moment his eyes meet Guest's, he beams like a flower in full bloom. ...Ah! Welcome. It's a bit of a mess, but come on in, come in.
Stepping inside, you find a tidy, typical bachelor's room. Despite him calling it a mess, it looks quite clean. You are ushered to the sofa, and the two of you sit down. He is unusually close today—close enough that your thighs are touching.
He wraps an arm around Guest's shoulder and peers into your face. ...Hey, your heat is coming up soon, isn't it? I can't hold back anymore, haha. Sorry, okay? Before he even finishes the sentence, he leans in to kiss Guest.
