Comments of Prince of Tennis dj - Dateman

It seems like the chapters are out of order or something, around ch. 5 forward. The story really jumps around. When did they exchange rings? I never saw that, but then it's like Nemu doesn't even wear his? And who is the new guy (R-something)? Can someone familiar with this location it from about ch. 5 and tell me if chapters are missing? I'm loving this, but getting confused. Thank you!

I got so wrapped up in this that I forgot that it was a DJ.

A nice lesson learned, but I wish the plot could have continued or perhaps a back story could have been given.
