I love this series! I hope they got licensed & gloriously fully uncensored someday. Anyway, chapter 18 should be the final of the story.
Enjoy!

The fact that Shirogane is featured on the cover prominently in 1,3, and 4 just shows that the author knew who the best girl is.... might also be author favourite since MC is very persistent on impregnating Shirogane

The story really went off the rails. Oh well, at least Shirogane solidifies best girl status.

The only one who actually got what they wanted was Shiori. NYAAAAAA~

Agh! You can't just introduce more girls as the cliffhanger. Thats cruel. Also at this rate MC is gonna solve the birthrate problem all by himself.
