Yaoi/ shounen ai / BL Isekai

Forced to marry a male wife, blocking his path to the throne. But as he was chased and abandoned by all, only the neglected wife stayed and died for him. Regressed the day after the (trigger warning) wedding night, Prince swore to repay and devote this life to beloved male wife.

Acceptable ex-trash redemption. It's basically lovey dovey story of a married couple with a terrible start mixed with ancient china court plot. Understandable why LN is so popular.

With the villain system, his job is to bully and traumatize ML and lead the novel to the perfect ending... But isn't the ML in each world acting a bit... odd?

Hilarious. Hardworking MC. Could have done an excellent job... if not that ML can read people's mind XDDD Gets along with system host (he signed the contract willingly to get a specific reward). Though it would be usual QT but plot went insane (in a good way). "Vive la Résistance"!
