I think mc and ml both are at fault. First of all mc like both sides of yura after the development so he should've sat down and talked about everything with him properly and pushed him to get some psychiatric help instead of leaving him to deal with all of this on his own even though he saw how tiered and disassociated yura looks , i get the mc's personality is not one to do that but where is the character development?also after yura found out mc knew something he lashed out at him for something he did after yura himself pushed him away is not mature. both of them need to seriously sit down and have a proper talk and why is jaepil a psychiatrist? like that man didn't do one positive thing to hely yura psychologically.....that being said i really love this series it kinda feels realistic not sure because i have never met anyone with DID and it probably will make it into my favorites.
