so i prefer something like from far away and white dragon where the main character girl depends on the main guy character.

there's nothing between them at first, but then they start to fall in love. the main girl character should have a cute personality where she wants to help the guy but knows she can not do anything, instead she does what she cans. something to that effect.

Until death do us part, sort of.

Mugen no Juunin - this is true at first, but later on she actually manages to save him once
Ibara no Ou - not sure since I finished this long ago, but I do remember that she had to depend on the main guy heavily for survival
Wolf Guy - kind of, since the female teacher is pretty powerless but tries to do what she can for the protagonist
