It's just a shame because it seemed like he really l understood bottom and listened to his especially when they had the deeper conversations about why he did that job only for him to turn around and be like oh he's good at sucking dick cause he sucked those older men which shows the complete opposite that he didn't actually listen. I'm sure it was just the authors quick way of showing jealousy in a sis story but I wish it had been done a different way. Just kinda left a bitter taste (ironic given the end of the chapter lol that's definitely gonna be a bitter taste)

i think the sequel might explain this behavior. i don’t read japanese but the gist of it is that one of his exes cheated on him, which casted doubts on his future relationships (based on pictures and context clues). so him not believing kai might’ve stemmed from that. or kai was just that good at it (better than his other experiences), that Yuma spurted whatever was on his mind without thinking
I'm suprised to hear he thought bottom was doing any of type of sex stuff with clients because he was a sugar baby when in the story bottom explicitly said he didn't do sex stuff it's was especially weird that's he was surprised when uke said it's his first time and even replied but you were a sugar baby even though he had this info and in the last chapter bottom said he was the first man he's with so it's just a bit weird it seemed like top understood bottom didn't have that experience and didn't even know hoe guys fully did it so just a bit weird didn't really fit with the rest
