See I'm right, he's Suho 💀 but I think the real killer is the childhood friend?
I struggled to accept he was Suho, while you can fake a face with surgery in dramas, you can't fake biometrics. But, the biometrics issue was resolved in this episode, and I'm in a state of jaw-dropping disbelief because, in K-dramas, the obvious suspect is usually a red herring, though turned out that he was not the killer but definitely a stalker number 3!
The insurance investigator guy, who was against the FL in the case, Now, will be working for the FL (secretly), in this very case, I guess - will be a fun ride!!
