I had checked that bit couldn't find the falg icon mentioned D: Perhaps it's 'cause the sight was updated... but there must me a way! Right?? I mean, scanlating groups do make works appear out of nowhere... I just wonder howww TwT

Thank you a lot tho! <3

Were you able to upload?? I also wanted to put a new manhwa here. It has been two days and no one is approving
