I read shojo/josei 90% of the time and I know you don't like those genres unless few exceptions, so I'm afraid I can't help. And the seinen I've read recently is extremely fucking depressing, so.

Uhm, but still, have you tried Yankee-kun to Megane-chan? It is quite fun and it's not technically shoujo, despite the romance undertones. Also, I'd recommend downloading the Layton movie as soon as it's out because it's HILARIOUS and LULZ.
