HELP

Anyone got the link to that one yaoi manga where the mc is a transmigrator and bcs he knew the plot he stole the original mc's place by pretending to be a seer that can see the future and when the original plot ends, he 'lost' his seer powers and ended up getting scammed. His fiancee sold him to the original mc and then original mc drugged him to force his way into him (literally) the original mc is a blond guy, yandere. The mc is shorter with a black hair plspsosp I need to reread this
