Such a cute story! I do think there were some loose ends that never got resolved (like we never saw either MCs transform into their animals) but it was fun to follow along. Thank you for translation!
So I was right about it ending soon but goddamn, I was thinking there'd be like, 2-3 more chapters, but not this chapter, lol. Oh well, it was fun while it lasted.
My immediate guess would be that March on is probably meant in the same way as "Step forward (into the future)" would be. Though I also have no experience with weddings so I could be wildly wrong.
For a series that started off so well the ending is very underwhelming. A whole "I don't want to treat you like a broodmare" vibe ends with an unplanned pregnancy and marriage... Like what's the point supposed to be?
