I’ve read this novel some time ago, i think it was mtl but i don’t remember. The MC goes back to his younger body and decides to marry his big shot “uncle” (not really related) to suppress his enemy, who is the uncle’s son. Rich families would send their kids to be raised by the uncle(?) and the MC was pressured by his family to curry favor with him. Later on it’s revealed that the uncle had transmigrated years before the MC and was already in love with him because the MC was never scared of him. I also remember that the MC studied art before his transmigration, and after it he decided to study economics to compete with his enemy. Again, i’m pretty sure that i read it on MTL so it might be really confusing, sorry.
I think i have read this in wattpad. Are you sure its an uncle? I have read the same plot but. I think its not an uncle. I don't know, but I also forgot the title and was trying to find it. give you a feedback once i found it.
