Genzo from Cheeky Angel is the one of the funniest characters ever! and sooo cuute 😃 is there any other manga with characters like him?

You could I'm Doushiro or Ocha Nigosu by the same mangaka. There are characters that is pretty similar to him.

With the genzo feeling u mean. Madly in love with the girl and do funny stuff trying to get her heart... or the Manlyness? I hope you arent hopping for both at the same time.

if you go with the funny manlyness i'd say that guy in Belzebub got a genzo feeling or maybe the Yankie in [Yankie-kun to megane]

With the madly in love and funny guy i'd say the new manga from the mangaka of law of ueki "takkosomething

Maaybe Ichigo from Chocolat. 'Cept he doesn't fawn over the girl...

But yeah definitely Ocha Nigosu by the same mangaka...
