It either Aragorn in LOTR or the "manly" Elfman in Fairy Tail..(ok, I just spew some nonsense)..
I think the nearest bet is Chocolat by Kubonouchi Eisaku, the mafia family tried to raise a 16 years old spoiled girl & using a really MANLY way..
Another one is Sand Land by Akira Toriyama, its a one shot, but, there's an old man character involved in this story tried to co-operate with good-behaviour demons.. Well, he really can takes a good care of the demons in his ways.
(& I always thought, if a man taking care a child or something like that is considered as manly, then, Watari (Death Note) is certainly the manliest of them all, upbringing L to his intelligent state is simply awesomely MANLY! Its really a shame that both are already goners..)
To find out a girl's faults, praise her to her girl friends
Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. THAT'S relativity
