Holy crap this one conversation added layers to Osanai. We figured she was crazy in the head, but this furthers that point by 1000%. It was an interesting thing for me that Sanae, whom Kengo wanted to help leave the group, was in full contact with Osanai. Even so, much as threatening her. I guess it serves the point that going to someone like Kengo wouldn't solve the problem. Essentially, Osanai was getting involved no matter what. Though the lengths that she calculated and planned is really insane.
Regards to Sanae before they went and engaged Isawa, which would have made the crime just kidnapping after Kobato and Kengo saved Osanai. Essentially, the plan was to give Isawa an even bigger punishment by letting the police know of the kidnapping before Kobato and Kengo arrived at the scene. Kidnapping for ransom is obviously a higher crime.
Everything was staged. Now I am curious how Kobato feels about all of this. I still think in many ways the friendship between him and Osanai has been well done. In many ways, Osanai's crazy genes kicked Kobato's crazy genes to execute the plan. The fact that the whole sweets plan was to also help her communicate with Kobato.
It's a bit of surprise for given how well they showcased how Osanai loves sweets. You wouldn't think there was anything more to the Sweets Summer Plan beyond these Osanai spending time with Kobato. During this conversation, Osanai eats up that parfait, and I am like na this girl genuinely loves sweets. There is no denying it.
Osanai is genuinely scary and she is greedy. Getting to enjoy the sweets with Kobato and execute her plan against Isawa at the same time. I really excited about the final episode next week.
