The RAW gallery had pages 36-50 left in Japanese. Basically these last 14 pages was just pages 7-21 but without the Mosaics censoring over the heroine eyes. I basically just applied the translation over the Japanese pages so the whole gallery is in English.

So he just did a cut-in of another girl. Who was that girl? Anyway, while the guy should have confessed, this protagonist is just disgusting. I really wish that there was at least one story where the NTR guy gets raped in the ass in the end and then brutally killed or something.

Fuetakishi always STARTS really good series, but then trails off and never finishes them.

I have no doubt that MC fucked prez too, and wanted to troll one of his "friends", we knwo he have no problems with fucking girls with boyfriends or that a friend would like to be with.
So that was to keep the ruse longer or maybe he used a filter on his phone.
Sadly the serie ends with this chapter.
