I'm looking for a manga where the protagonist has to enter into a relationship for sacrificial reasons (e.g. girl sacrificed to a dragon god to keep her village safe; maidservant who lets her master take advantage of her because she thinks that if he fires her, she'll lose the means to support her family). However, eventually real romantic feelings develop within the protagonist for the person they've been "sacrificed" to.

Basically, a manga where the main character enters into the relationship for OTHER people's good (NOT just his/her own survival), but then ends up falling in love for real. Doesn't matter if the person they're falling in love with still sees them only as a sacrifice or not - they still fall in love.

Gay or straight relationships are fine. (My scenarios were girl-guy scenarios, but I'm also okay with guy-guy or girl-girl!)

Examples: Bride of the Water God and The Royal Fiancé (dubiously).

ANY genre EXCEPT hentai is welcome.

Help me by recommending some titles, please!

Shinobi no Onna - 2nd & 3rd story

That's all I could find right now; I'm too lazy to look further.

Thank you both!

I also just realized that Okane ga Nai is a yaoi manga featuring an initially sacrificial relationship (to compensate for a cousin's debt). I really can't stand it, personally, but it DOES fit the theme...

Shina Dark has that covered

*Stepping on roses-I think it could fit with what you are looking for
