THE ULTIMATE SEME!

Mcqueen from Walk on Water fullfils all of your criteria, very sweet. Very not suitable being an uke, but you can if you like big stoic uke.

My personal ultimate seme, seme god is always Asami. He just can't be bottomed by anyone (even Halvir from the same mangaka), it just can't happen lol.

Ehh I don’t think any of the seme’s you’ve listed have that last requirement, they all just do wtf they want. But they really are top notch beast seme. They are just all rapey. So

I kinda Think the seme from these are really great... despite their lack in some areas

And sadly if this had more smut it’d be good http://www.mangago.zone/read-manga/a_paramour/

I’ve only read the first couple of chapters of viewfinder, but didn’t the guy you’re talking about (asami) shove a camera up the journalists butt?

haha yep, they started off like that but you'll definitely see the development on their relationship at the later chapters

yes exactly. I only said that they were the ones who are commonly portrayed as the favored seme by most fans, that's why they don't really fit for me as the ultimate seme (except for Dojin, I guess) and Asami does start off that way but he actually develops his feelings towards Akihito

also yup, despite yata's demeanor, he has the strongest stamina and sex drive. Damn, love that manga so much because he really loves Momo and my favorite from Harada's works
Tomoharu is such a boyfriend material. I suggest you read ROUGE by Katsura Komachi, loved the seme there and they have a healthy relationship
haven't read Paramour but thanks, I'll be sure to check it out

To me, it’s Shizuma from Therapy Game. I know he’s hella different from all of the seme you listed, he’s neither an overbearing or proud af guy who’ve done shitty stuff in their life, Shizuma’s just a sweet guy overall. He’s not the puppy seme type imo, he’s more like the naturally caring type who makes little gestures looks so meaningful and is just pouring all the love he has for his lover. There’s this chapter where it shows how Shizuma had a book for longtime gay couples and there’s a picture where there’s two old men holding hands affectionately while wearing heart-patterned sweaters and Shizuma said to Minato that he wanted to be like them. Bruh, how could you not melt? Shizuma’s friendly and helpful personality might have made Minato very insecure but Shizuma just knows what to do to reassure his lover. He’s just “that guy” who stays by your side and dotes on you in his own way. He’s definitely boyfriend material.

Also, my 2nd ultimate seme is not from a manga, he’s from a chinese novel called “Don’t Pick Up Boyfriends from the Trash Can.” His name is Lou Ying and his personality is also pretty similar to Shizuma. He also shows his care and love towards his beloved in his own way by making sure to let his beloved be the most comfortable, treat him in the best way, always offering to help him. He’s just hella sweet and btw, Lou Ying is also not a puppy seme, he’s the caring type. Our Lou-ge is the definition of husband material.
