Comment by Psychopath on Pure Love Operation - Chapter 83

@Psychopath

I'' sure Raym's mom is dead and she was eunhyuk's piano teacher, Raym hoped that eunhyuk's father was her father (i mean they had an affair) but Raym was wrong and hence they are not half siblings like she hoped for. 

So i think raym and eunhyuk got close and eunhyuk said that he will be his oppa/brother .

@Psychopath
1. Raim's mother is dead, and she is not that music teacher bc she's too young. It's still unclear as to wether or not she was involved with Eunhyuk's dad (maybe she was with the guy in the picture and cheated with Eunhyuk's dad, who knows..)

2. Eunhyuk thinks she's his half-sister and said he will take care of her to make up for his father's abandonment.

3. Raim knows Eunhyuk is not really her brother but takes advantage of his trauma and the fact that he said will be her brother to trap him and keep him close to her because she feels like she doesn't really have anything.

@kyoko thank you so much dear... I have one more doubt why is eunhyuk think she is his half sister? Because the story never showed that eunhyuk's father and raym's mother had an affair

@Sago if raym's mother and piano teacher is same... How is she still alive  in the chapter (83 or 81idk well) where eunhyuk had the piano competition (if you didn't understand I was talking about this chapter where suae and eunhyuk) kissed

@Psychopath ohh now i get it , so you're right about raym mother not being the piano teacher

@kyoko  , if she suspects that she is his sister then why she try to get him into a relationship??
