Fuyuzora Kogarashi. - Yuuna and the Haunted Hot Springs
Rough childhood, learned and matured and cares about the girls in his life. Is not dense. He vows to protect the women that love him and earned their trust.
Kamijou Touma - A Certain Series
Rough childhood, called God of Pestilence. Has had many things happen to him but still considers himself just a normal high school boy. Shatters illusions of those that are blinded by their own ambitions and will help even those he once fought. The guy genuinely is a good guy and you can argue that the girls that love him truly do and he handles himself pretty ok, he is dense but I dont think hes super dense, he knows he wants an older girl or has hinted at it.
Bell Crannel - DanMachi
Earnest in trying to attain his goal, mostly decent guy, have many girls in his life that would be great waifus. Has had great growth in the light novels personally and with the women in his life.
Satou Kazuma - KonoSuba
Guy is legit. Reliable and pervy. Has a terrible group that he helps shine and yet he keeps honest with his intentions of perversion and just lazy attitude. Like Touma, yearns for gender equality. Is not dense, has bad but not terrible love luck.
Goblin Slayer - Goblin Slayer
Badass. Doesnt mince words. Smart. Earned the respect of others and the admiration of the women in his life by staying true to who he is and yet still shows them glimpses of a side that shows that hes a great guy.
