I also like unique pairings, an example of shishi mo kobamazu. It also have a taller and muscular uke, the same as this one. But tetsuya doesn't have any uke appeal, he's not cute at all, he's just cool, the contrast of the uke in shishi mo kobamazu.
And no, I'm not complaining duh..., I'm giving my opinion without insulting the characters, the manga or the author. You're thinking too much about a simple comment.
Im not saying you are insulting the character. There is a difference to that so don't overthink my comment too. You and I had much enough freedom to express our opinion (๑•ㅂ•)و✧
Only, being "disappointed" sure sounds like complaining to me, IDK. I see a lot of similar topics on "seme not being enough of a seme" or "they should switch" on a few mangas like this. Kind of a downer tbh. My comment is more about imploring people to can we just enjoy these kind of seme and uke "that does not look seme/uke enough"?

Overall is good and I liked the plot but I'm quite disappointed that Oumi is the seme and tetsuya is the uke. I'm super picky about who the seme and uke is. And usually, I prefer a taller black haired seme who gives a cool and sexy vibe and uke who is cute when doing sex. Oumi is cute to me but he's not really cool much and tetsuya just isn't cute to me but he's sexy and hot. But I guess I still liked it though for me, it's a good manga to kill my time with. ╮( ̄▽ ̄)╭ it's a 50-50 I guess...
