Some anime end ahead of manga that started way earlier but in exchange for that they lack explanations of events and story, leaving some holes, I prefer a good manag covering everything to a rushed plot.
People thinking Makoto is weird for his decision but are ignoring how he said sex should be with someone you are thinking or marrying, not after marriage, MC is still just a kid that had a bit of a inferiority complex on Earth given his weak body, Tomoe and Mio are beautiful, but still not human, the thought must be in the back of his head, they are his servants, he doesn't want to use the contract to force them to accept him, need a bit more to be sure (and he doesn't even know that for the contract ratio they are technically slaves and he could force them to do anything with one decisive word).
I wonder why the TL is suddendly 3 months behind the raws, the team did make othe releases so it doesn't look like IRl stuff made them unable to work on stuff, could even be that team members that only do Tsuki are unavaiable.
