I'm looking for a BL quick transmigration. I only remember this one arc where the ML has the ability to read minds. Then MC sealed(?) his true thoughts and only let ML heard what he (MC) wants him (ML) to hear. I honestly don't even know if the ML I'm talking about here is the real ML, but I will just assume that he is Anyway, I forgot what his actual task is, but when they first met, MC let ML 'heard' him talking with the system about finding their mission target and MC deliberately find the wrong person, because that person and ML has the same jade necklace maybe? I forgot. So ML know that he is MC's mission target, but didn't tell the MC and just watch as the MC tried his best to gain the wrong person's favor. MC is a mermaid in this world, and he was picked up by the professor from the school he and ML goes to. I think the professor and the wrong mission target are also in love with the MC. Edit: So I remember some more of the plot MC was blocked in a toilet by a few girls, the leader of the girls is mad at MC because her fiance was interested in MC? But MC asked her who her fiance is, and then he pointed at the girl's friend and said "but I saw her kissing with your fiance" the girl then said she already knew about it and she really hates her fiance but didn't know how to break up with him (I think they were either whispering or the girl asked her friends to go out first). So MC told her the 'white lotus' way of breaking up with her fiance and make the fiance regrets it I think. That's all I can remember for now, please help me
Learning God in Hand, I Have the World Maybe? I don't know why but have a vague feeling the first arc was about the ml being able to hear mc convo with slag system.
