Can we recommend each other lesser known manga that you've enjoyed? There's a fuck ton of manga out there and it's always nice to discover new stuff.
Dunno how well known Teppu is but its great
I really liked Happy World, starts off a lot like Negima! did by it being haremshit but then going more shounenshit later, while still also later being pretty heartwarming/wrenching.
Pic isn't a good representation of the series as a whole.
I hope you're ready to cry like a little bitch.
