It's a historical Chinese novel I think and there was no reincarnation or transmigration MC is supposed to be the fiancé of a prince, prince goes of to war or something and brings back another country's princess as lover... So king asks the prince to take MC as second wife because MCs father is the prime minister or general or something . Mc wants to break off the engagement and asks her subordinate to ruin her name ( MC has a secret identity as some gentleman who knows martial arts) but was unsuccessful ... From the summary it seems like a tragedy . Mc and the prince is fighting, the other wife is dangled in a tree (?) Mc sees she's slipping and tries to help, but prince thinks she's (Mc) trying to hurt the other wife, so attacks and make mc falls off the cliff.. Everyone is stunned ...(cue dramatic music) . . This was the summary...but as far as i remember the story didn't get translated this far and it got dropped i think ... I don't even remember if this prince is the ml or there's someone else . Does any of this rings a bell to anyone ?? Thanks in advance .
