I loved this chapter! This is why I love Skip Beat! Things don't always turn out the way you expect them to. And I completely agree that Shou is being an ass by trying to monopolize Kyoko's mind. Before, I was sure that it was because he has feelings for her. Now, I'm not so sure...but there could be two reasons why:
1) He could be in love with her afterall, and is just having trouble accepting it since he's the one that dumped her, and he's known her for practically all of his life. In that case, Shou's problem would be a matter of pride.
2) Maybe he needs her, maybe not romantically, but in another way. All of his life, he's been pampered by her, and now that she doesn't want anything to do with him (except for revenge), he might be feeling odd because he's had to adjust to a life without Kyoko. This would mean that Shou is just being selfsh as always...which I remember it saying somewhere in the manga that if he were to be described in one word, then it would be selfish (i might be wrong though)
As for Ren, I can understand why a lot of people are upset about his reaction, but I actually preferred it. I know that just about everyone was hoping that Ren would comfort her, and finally make a move, but I honestly think that it wouldn't advance the relationship at all. Though I've seen several interpretations to this already, I think that Ren's remark at the very end was a sign of him losing control to the point of going out of character, and showing his true self. All of this time, Ren Tsuruga (or Tsuruga Ren...which flows better in my opinion) has been a role that he has been playing for five years, and may I remind you that Ren and Kuon are two different people. If this couple is going to live happily-ever-after (which I hope they will) then Kyoko has to fall in love with Kuon, not Ren. Though Kyoko has seen some instances where he goes out of character, most of the time, Ren is very good about staying in control. So I've been worried that Kyoko would be falling for his fascade and not the person behind the mask which is why his reaction made me feel somewhat relieved.
