Some parts were implied meaning the readers will force to analyze and it's good since it's a yakuza theme story. It will make u part of the story line... The author is really good i love it.
I totally agree with you. I was also expecting a story of him instead of his ex or like they would reconcile in the end but damn it didn't happen tho its also part of what a true relationship end up sometimes. ╥﹏╥
The Mangaka should continue the 1st story. It's more interesting...
