The tea which Kaede serves at the end is written as "千日紅" and Sennichi's name is written as "千日", so this college kid definitely just picked it for that stupid pun.
And with that, I close out the manga I've been working on for over 20 months. Which damn, I had not realized just how long it had been, especially after the last manga only took a little over 3 months for almost double the number of chapters.
I feel as though this ending was a tad rushed, but at the same time, it likely couldn't have come out any other way with the way the manga really pushed the overarching plot to the side.
I will be putting my focus on making it out to graduation for the next several weeks, but with absolutely no summer plans ahead for me, I'll definitely be putting out more translations soon enough. If you have any interest in following my work, please look to my group page on the forums for updates!
