@Goldberg err, I don't really think the ending is proper for that. Imo it should've ended with them taking over the dojo while being a family since then you can say Tomo is happy. this ending fits more if this was a 5 chapter manga.
Said what I thought about the series on the prior chapter, but did want to add huge thanks to the translators for sticking with this for such a long time. Must've been really annoying to have to go about this over and over again over such a long period of time.
