Is there much Shonen that you'd describe as "heartwarming", though? I like stories about personal emotional growth, and magic. Wasn't using "she" for virtue signalling, just as what seemed to me to be a statistical fact. There's one I can think of with a male protagonist, and his great aspiration in life is to be murderer, and he targets his classmate, who is a tall and slightly dim-witted model ... and ends up filled with protective feelings toward her, which begin when he impulsively lends her his intended murder weapon (a boxcutter) to cut some card for a school project ... and by the end of the series they're going round a mall together at Christmas, holding hands. That was a pretty good one. Recommendations for ones with male protags are welcome, if they're not full of tanks and battles and so on.
