From the article:
This year’s 45th issue of Akita Shoten’s Shōnen Champion announced on Thursday that Toshinori Sogabe’s Yankee JK Kuzuhana-chan (Delinquent High School Girl Kuzu-Hana-chan) manga will go on hiatus due to the creator’s health. The series will resume serialization in the 49th issue on November 7.
Same happened with date a live. The manga has been abandoned ever since.
