Yeahhh it's quite sad cause this author has one of the best story, like the balance humour, characterization and lovely characters design but i kinda understand their decision cause this manhwa industry is soooo harsh to their artists, some even speak up about it and not so long ago, there's this art exhibition and the theme is "overworked manhwa artists" i remember there's this manhwa artist that get miscarriage...
So i imagine this author/artist was in similar condition before when they wrote "uncanny charm", maybe their workplace condition is toxic too or they can't keep up with the weekly schedule and that lead them to choose to only write short stories from then on

I really loves every works from this author, too bad they don’t want to make any story with more chapters anymore :< I hope they will changer their mind tho
