I guess everyone has their own favorite/s Seme/s, depending on their tastes, dear.
Asami is a very popular character in the Yaoi world especially as strong male/Seme, but he's not my fav Seme either. He's just too cold and abusive to me, and too unrealistic; he's a perfect character for fiction, but I doubt he'll make a good boyfriend IRL.
I know, I want more! I wish there was another volume. I wanted more sex, but it’s kind of charming Miya just flat out said “I’m inexperienced and I’m worried I was bad” and instead of brushing him off Shio responds by going “ok, I don’t know WTF is going on either, let’s clear our schedule and research this together”. I don’t think I’ve ever seen that in a manga before.

Be careful, there is sexual violence and rape in this series.
Most favourite seme I’ve come across, the personality is just super cute. Wish there were erotic sex scenes :(
