Nope not really i mean there is isea who isnt the worst since he is kinda just acting like a normal boy ;-;

And then there is hentai where its impossible to find a good one with a story since all the males take advantage ;-;

Depends on what u mean by gentle

Smh... there are many, many nice guys in anime, but ppl who only watch shounen might say otherwise.

Some examples:

+ Usagi Drop

+ My Roommate is a Cat

+ Honey and Clover

+ Fruits Basket
