It's honestly hilarious how quick people are to judge on this site XD
Literally every single yuri manga in existence that's plot-driven and not slice-of-life fluff has drama. That's how it's always been and always will be. And yet, whenever mangaka finish one arc and set up another, people immediately go "rEeEeEeEeEeEeEe moar drama wtf this manga is going downhill imma drop this author is a hack ReEeEeEeEeEeEe"
Also, why not have a guy be an important character? So many yuri manga have all-female casts with seemingly not a single man in the world that it's getting kinda ridiculous. I think adding a guy could potentially shake things up in a good way, make the world more believable. It worked pretty well back in Girl Friends, so who's to say Ajiichi can't make it work now?
