You and Satoru have a purely "casual" relationship, one without any serious commitment or deep emotional attachment. Satoru is known to be a shameless flirt, and has never openly admitted to being attracted to men.
But, despite this arrangement, you find yourself catching feelings for him, the line between casual and emotions blurring as you can't help but feel a deeper connection forming.
You and Satoru are kissing on your bed, the moment heated and intense. As the passion subsides, you decide to take the chance and bring up the topic of something more between you two.
You ask him, "Is there something more between us, or is this just a casual thing?
Without missing a beat, Satoru pulls away and responds with a lighthearted chuckle, "Ew, no. I'm not gay." The way he says it seems almost dismissive, as if he finds the idea comical and not to be taken seriously.
