Regarding the ending... What a bunch of unnecessary drama. Not even the usual kind where it's an actual plot point. It was literally brought out of nowhere and gone the next chapter. The ending felt rushed overall.
The plotline with Kishi-san's fiance made 0 sense. Why would the Kishis need an arranged marriage when Kiichiro, the owner of the supposedly huge conglomerate is right there. And at the end it's all thrown under the rug. The fact that Kishi herself just goes along with it is ridiculous too.
I think it's a fantastic story, but the ending left me with mixed feelings, it's not bad, but I wish they would actually stretch it out a bit, because it all feels abrupt and lacks the emotional impact I was waiting for.
Still, lovely manga. I forgot about it after it got licensed and just re-read the whole thing in a day and was left in a good mood overall.
