it's manga with an irregular publication. The reason why it feels rushed is because the author can't spent too much time building up a story.
so make a good story and don’t make an badly written one if your story is publicated in such an magazine!, like let’s not make excuses for the author!, if they can’t make an good manga for this type of serialization the don’t make one in the first place >.>
it's a filler manga for a magazine that suddenly lost one of its major serialization, what did you expect?
Did they lose My Cute Kitten too? Or was it just Liberty? Or one of the other series? It seems Hakamada Mera is holding down the fort right now, and it's probably not a good sign that they're reprinting Morinaga's The Secret Recipe. I hope all is well at Galette, although you won't see me complaining about Tsubomi stories being republished!
It's probably also helpful to note that Galette is a (regularly published) quarterly magazine, half indie and half commercial, and the editorial staff has little input into what the authors create unlike something like Yuri Hime. It's also the longest running yuri magazine behind Yuri Hime, so it is not a throwaway or bottom tier place to be published. (Not aiming this response at you guys, just getting the info out there)
