Last few chapters feels very abrupt so it's probably axed. Then again there's not a lot you can do with premise like this, so I feel like ending this early was better instead of rehashed jokes and cheap forced drama for 100 chapters.
I don't know if this just me, but the artstyle took a nosedive for some reason. Especially the MC. He looks rather bad in the past few chapters. As in, the artstyle / face looks pretty bland, like the artist stopped trying. He was fairly attractive in the first few chapters.
