The Substitute Bride

My mother hates me. She says my legitimate elder sister can't go to the Netherworld to marry for an alliance, because she's frail and can't endure hardship.

My master hates me. He says I'm cruel and heartless, and that I don't care about my legitimate elder sister.

Everyone in the sect wishes I would marry in her place.

Fine. I'll do it.

But why did they all come to regret it later?
