he did lost his memories but he's just smart so he was trying to make sure they're really married, he got suspicious when she keeps calling him w his full name and how she acts around him & the stuffs around the house where the only things screams "male" is his room like there was no signs of cohabitation
he'll get his memories back, tho its like the climax part so almost at the end of the novel
if u want more spoilers/question lemme know, i really love to talk about this novel because it was so goooooood I recommend it

the brother will register their marriage so he got convinced that they're really in a relationship (tho he thought it was abusive one so he was making it up for her)
also the reason he stopped crying when listening to classical music is because he's a genius celloist (plays cello when he was younger) and they actually know each other as kids (he's the reason why she likes trees! though they didn't knew each other's face, if you want me to elaborate it lemme know)
when his memories came back, he crashed out (ready your tissues)
and major spoiler

she's pregnant when they separated
during that time, the insect doctor (child) got into his brothers car & was held "hostage" at their house so she needs to work in their mansion so the child can go home then he'll realize she's pregnant
*there will still be a lot of plot so i recommend you guys read it because it was really unique and beautiful tho be prepared because there will be a lot of crying
especially the part where Kwon Chae-woo (male lead) was hallucinating and he was "recreating" the scenes he regrets to make it right (he knows he got drugged but he still wants to make it right even tho it's all an illusion)
and the part where he's playing cello in the rain, its a masterpiece
Why do i have a suspicious feeling that he didn't lost his memory
