So, dear friends, after rereading the last chapter, I had a feeling that Rika did not know about the problem of Soska with erection. I believe that she will learn about it from Akiba during their conversation, when Rika tells her about her real plans.
Sosuke's next actions will be related to Marupi. Soske will go with Marupi to her room, where he will demand Miyabi's phone number from her, blackmailing her by knowing that she is Kanebayashi (Miyabi will tell him about it). But it will turn out that she has already given the phone to Iwabuchi.
Observing this from the side, Rick will confirm what Akiba said, and will understand that it will not be possible to keep Soska in this way. She will also understand that Soska and Iwabuchi should not be allowed to meet. Then she'll run to stop Soska. That's why Akiba told Misato to watch from the outside so that she could see how Rika was panicking. Rika will meet Soska and there will be a small dialogue between them, where there will be an apology and answers to the question "why". To this, Soska will say that first you need to get access to the Iwabuchi server and delete all the data from it, after which they can calmly talk.
They will go to a party where Iwabuchi will try to break Soska's heart, but he will not succeed. Everything will be quite simple, Rika is pregnant with Sosuke, not from Iwabuchi. And that was her backup plan to keep Soske. That's how Rika will break Iwabuchi's heart, because all this time he thought he was his child. In desperation, he decides to publish information about Misato and Rika, but then Satsuki comes on stage and takes the phone.
