the reason is shallow but quite reasonable.
He just wants Yansheng to love him for who he is and not because he is his savior.
Even if they tell him I don't think yansheng would ever believe him cause he's a fucking stubborn bastard! And he's such a fucking stupid bastard! I mean almost everyone is trying to tell him that his bitch is just deceiving him but the slow fucking bastard can't do a proper investigation to know the truth!!!!!! ─=≡Σ(╯` □ ´ )╯︵┻┻
he'll eventually realized luoan is fake but regardless of his character development after that, he's still a trash.
I dont understand why wen doesnt want gu to know the truth about who saved him that day. I hope theres a strong reason for this unless its just author just trying to make the misunderstanding to be dragging for more chapters...
Almost went mad when the brother was just about to reveal the truth and the mother just had to stop him.ergh...please let it be a good reason
