Thanks, bro. What I really want to see happen soon is for Sakura to learn the truth and resolve those issues, so that readers will stop being angry with her.
The answer is on page 9 of chapter 131. I'm sure that room belongs to Sakura, and that page also reveals the relationship between Sakura and Yuma.
P.S. That page caused me pain.
Sometimes I don't quite understand Sakura's thoughts and feelings. In Chapter 130, when she sent a message saying she wouldn't see Shinobu anymore, I assumed she felt guilty about sleeping with Yuma—especially since she seemed sad when moving house. Yet, in Chapter 131 (page 9), we see her...
Personally, I don't think Katsura Airi would do something like that; it would seem a bit sloppy. The solution is simple—just like what others on the board have suggested. I really wish Airi-sensei would read this message board, too.
Personally, I think Sakura and Yuma continued having sex after Chapter 129; this is evident from page 9 of Chapter 131, where they are still at it, though they had moved to Sakura's bedroom.
P.S. It is so sad.
