to be fair, yaoi is usually porn without or w/ little to no plot (especially in mangas with little amount of chapters). I'm pretty sure this was made without the purpose to be anything amazing plotwise and moreso focused on dynamics and smut, explaining why it's so fast paced and barely having intent behind the actions of the characters.
Character complexity was most likely not taken to accountability. Because as what I've noticed in short yaoi mangas like these, male characters are often objectified and static rather than molded into the potential of what character depth they could've had
If you want yaoi with good character writing, smut, and plot, I can recommend you some
Character dynamics focus (light plot)

I just feel like this is really unrealistic, why most yaoi stories are, I just feel like this one was really weird like it felt out of place the way the characters spoke, I feel like no one would actually say those things. And also he asked him to randomly help him with his erectile dysfunction out of nowhere, which was weird that he said he had quote on quote “no one else” I don’t know. Just seemed weird like the uke was plotting on him the whole time but we don’t see that. Anyways, I don’t see why a playboy would just say yes, I mean I get it but at the same time… I don’t really. I don’t know, just wasn’t a huge fan of this. It’s okay. I can’t tell if I really liked it or didn’t.
