Secret's manga / #dumb mc(3)

tragic past, dont like the og mc bc why not just do sumn for the people to stop thinking bad things but then again i wont judge. i also dont like the og plot bc the ml just straight up fell inlove w her??? like doesnt he want to know her personality first like bro??? now im not certain what is gonna happen but the mc is so fucking dumb, like how can u not notice that the boy fell inlov w the mc and not think that he's the guy who'll marry ur sister?? like- u know what will happen bc the ml told u that if he doesn't get married, he wont be the master of the house, like what the fuck??? and the ml, i dont like him either.. the art isnt that good too. the og nc just had a seizure, i think its getting better??
