Check one of the chapters ( う-´)づ

Hello i can help! So when you go to the manga on Mangago on the left side of the screen there is a little flag. Click on that flag and it says "report a problem" on the bottom there is "upload chapter" click on that and it should explain the rest!! If something is still unclear please ask. Btw if you don't mind whats the manga?
