I don't think this is the only chapter. Seriously, who is Rudy? And is there any relations between Rudy and that wolf? Something must have happened. And how can a kid innocently played with a wolf. There must be reasons to all these! And I'm going to die in curiousity. （/TДT)/
My theory:
Kang Jinha really did rape Go Siwon and Siwon believes that it's the real Kang Jun while Jinha was nagging about this and that and whatever. Jinha disappeared and Siwon is trying his best to search him.
Reality:
No, he stopped. I thought so since the genre is Shounen Ai and it's too soon for 'that' but my heart was beating like crazy just now. I want to see Siwon with Jinha. Oh god, please.
