It's a shame that not just the incest part didn't get anywhere, but neither did the romance aspect of this manga. I hope it's only because it seems like it got axed, but it really is unfortunate that it lacked that direction at all for the ending.
That said, I disagree that this manga was trash. I surprisingly found this kind of... inspiring? I always lacked a direction by which to take my artistic career as a writer, not only advertising it but also emotionally. But with how this manga tackled this theme, it actually motivated me to start giving my all to my craft. Thanks for translating this!
