Maybe ch 200 won't be about Natsubaru
The symmetry between chapters 37-39 and 137-139 has already been mentioned before, highlighting how important these chapters are for each of the series' couples. Because yes, even though Saku and Subaru aren't together yet, they will be, we just have to keep inhaling the copium.
However, the end of chapter 189 definitely gives us food for thought regarding Kaorin's future. Obviously, a breakup is highly unlikely since there isn't any serious issue of that kind. The point is that we are going to see a more mature and serious side to this relationship, perhaps a minor argument so they end up closer, and I feel we might see this in chapter 200.
So, regarding their development, chapter 200 specifically just makes it look nice for a major step in the relationship to happen every 100 chapters. With every date they've had, they have been getting closer and closer. To mention a few instances, they would be the following:
- Ch. 59: Rintaro calls Kaoruko by her first name for the first time.
- Ch. 73: They hold hands.
- Ch. 100: Their now-famous first kiss.
- Ch. 116: Even if it's under the excuse of a horror movie, there is more physical contact, plus Kaoruko showing her desire for it and Rintaro being comfortable with it.
So, I feel their next big step forward could develop similarly to >!Love is War (chapter 220 of its manga). That's right, doing ir, having sex, but in a more subtle way.!< It’s a huge step for couples, and just like in the manga I'm using as an example, it’s a way to reinforce the connection they share as a couple, showing that no matter the distance, they will always be together.
Honestly, it’s a topic that imo could be handled further down the line, but as a comment in the chapter 189 thread says, it could be the path the series takes.
There are 11 chapters left until chapter 200; it's something that could happen before, after, or not at all. But with Christmas and exams around the corner, the moment could be built up for this to happen.
Obviously, not all of these chapters would be dedicated to this, since the upcoming ones will also focus on the whole group, and Subaru's birthday is close too. Still, the possibility of it happening exists. It might be a bit of an exaggeration that they can't see each other that much; from what I understand, they are in regular contact, just obviously not physical. In the manga's timeline, they will have gone about 2 weeks without seeing each other, and as I mentioned, this path could serve to make it clear to them that no matter the situation, they will be together.
And for Natsubaru, in case all of this doesn't happen, they don't necessarily have to get together right now anyway. Since both of them are going to the same university, and in this very chapter they mention the paths everyone will take, it could be that they make it official once they are college students, with more development along the way, of course.
