"Weak" Guy

Hello :)
I'm looking for dramas or movies with a guy, who's somewhat weak(er) than the girl (if there is a girl) or suffering (also internal struggle). This can result in the girl caring for him. With weaker I mean all kind of aspects.
What I have seen so far and have this theme:
Sky of Love, I give my first love to you, Bridal Mask, I can hear your voice, Good Doctor, Can You Hear My Heart, Closer to heaven, Maundy Thursday, Werewolf Boy, Boku no Ita Jikan, Triangle, Real, My Son, Noona, The Attorney, Hwayi, Juvenile Offender, It's okay that's love, Secret Door, Bad Guys, Healer, Kill Me Heal Me,Angry Mom (Jisoos character), Falling for Innocence, I Remember You (Min)
I hope my request doesn't sound too weird XD Basically I just want a show, were the guy isn't perfect and is struggling with something and will (or sometimes not) overcome it with the help of others. (If possible not too much comedy)

Thanks for the reply :)
I have already seen Secret Garden, Rooftop Prince (loved it), Gokusen (one of my first dramas ♥ ) and Tumbling, but nonetheless thank you for your recommendations ^^

And maybe Koukou kyoushi 2003
The story is intense and kind of twisted but sooo good. This guy has a very... unusual way of dealing with his weakness.
