"The new volume will come out on April 7th! The sales will decide whether I can continue to draw the series. Please keep rooting for me."
And considering that I couldn't find any follow-up tweet and the author's twitter is now advertising the new series, I'm afraid it got axed
At least to cheer you guys up, here's the self-quarantine special chapter drawn by the author:

Ngl, I was hoping to see a continuation of previous chap (how she went into his futon and they "slept" together), any kind of conversation or anything really... And this is already new year's eve so... Hope we will see it in some bonus chap or like a flashback in some other chapter...
