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.
