while rewatching episode 2 I realised something. it seems ho su recognised miji the first time they met (when she was acting as mirae) I think he suspected she's miji. and mirae too told miji that he can recognise miji cause he's the third person that can recognise them. and the main reason I think so too is because when he told her about the case she asked him how did he know that while he already met with mirae. he knows mirae is not supposed to forget. and when they met again during the weekend I think he definitely knew she was miji
