help me

this manhua has been on my mind for so long but i can’t find it. i’m pretty sure it’s a chinese straight manhua where the mc’s husband is cheating on her with her step/half sister or something? but the thing is mc goes to a hotel (i think that her friend booked her after the whole affair event) but ends up entering the wrong room and she sleeps with a guy (blue ass hair like radioactive blue) who she thinks is like a male escort that her friend booked? but like next day she goes to work and he’s some important business man guy and also her mother is a doctor?? or something??? and i THINK can’t say for sure but the woman the husband is cheating on mc with is pregnant


tldr; trying to find a (maybe) chinese manhua and the only thing i remember properly is mc’s husband/fiancée cheats on her and the ml has really bright radioactive blue hair
