My Mysterious Serpent Wife

My adopted brother made a name for himself during the potion competition by using a potion he had stolen from me.

No one expected the competition to be a ruse, but it turned out to be a scheme to find a husband for the serpent clan's youngest princess. She was born barren, cruel, and hideous.

That very night, the serpent clan delivered a marriage contract, demanding that the creator of the potion take the princess as his wife.

When my fiancée heard the news, she panicked and bonded with my adopted brother on the spot.
