Does anyone know any cool seme characters like ASami from You're My Loveprize In Viewfinde...

Not sure what it is about Asami that you find attractive, though. If you like his forcefulness, look under the Possessive Lovers lists that crop up in the sidebars. If you like his coterie, then you might want to try scrolling through some Yakuza compilations, or try looking them up under tags. If you like his looks, then you might try artists with similar styles, like Narasuka Rin: http://www.mangago.me/r/l_search/?name=narusaka%20rin ...
