A glorious conclusion, surrounded by lily flowers. They had a proper confession, said "I love you", and even more importantly, Kazuma finally said that Sumika was cute. The way she teared up at that just about broke my heart.
Even the supporting characters got redemption in the one-page comics at the very end. I'm so glad that Akemi's career wasn't totally ruined by that one gag, and now he's not only making it big in Europe but paired off with the German girl (after a phenomenal growth spurt, good for her). And of course, the Wingwoman Couple is set to reform the world economy one country at a time. Ya love to see it.
It's been years since I read this manga... At the time I was reading it on an iOS mangareader app. Coming back to it, while it definitely delivers on its fluffy chapters the middle section definitely got stretched out for way too long. At least a half dozen situations where only the perfect storm of happenstance kept them from being able to talk out their feelings sooner. That said, the way that they were able to come to a conclusion together even with so many ridiculous things keeping them apart is also kind of inspiring in its own way, I think. Chances are I'm probably not going to reread this entire series from start to finish again, cause it's really bad for my heart, but I'll still give it a solid 9/10. One could argue that it should be an 8, but I'm feeling generous.
