This story use to be interesting but now it lost it's charm. I feel the mangaka didn't know what to do with her story so she made this eno plot which doesn't add anything interesting to the story.
That's just chapter 1. They release it chapter by chapter, but it usually takes a while because of the process of drawing ,planning, and translating everything.
Discolated one jaw, probably an arm too and gave the third concussion oh boy it's a mess
