CirPhus was not about sweet love. It was all angst. Even the first time was more goodbye sex on Phus end. Ep 7…
I did see sweet love between Cir and Phu. Cir supported Phu, who was mourning the loss of his dad, talked to his cousin saying he would be there as long as he could, saved Phu's life by sacrificing himself and lastly hey had a sweet romantic moment (not in that order).
I think Cir knows his mother tried to kill Phu so he flipped and is acting demented. Once he resolves the issues…
I don't think he's pretending to have amnesia. In the preview you can see there's another Cir wearing black and this Cir is locked up in a mental institution wearing white.
