can i ask whatchapter should i read after the anime series/the movie thank youu in advance

I think you should start from vol. 5, but I'm not sure at all.
There aren't so many chapters, you should read it from the start to perfectly enjoy it. ^^

The chapter you should read after the movie is 29. I personally recommend starting from chapter 17 (where the movie starts) because a lot of the scenes werent included in the movie!
