I feel like there should have been more. I couldn't just accept that everything just resolved that easily. I mean, the uke might've suffered so much from hiding his true feelings and I can deffo understand that. The seme just seem to have a plot armor that everything will just work out in his favor. I wish there was more chasing for the climax. I wasn't satisfied at all with the whole story. At least, this is just my opinion.
I mean their back and forth took 15 years. Even if the story doesnt convey it...it really took forever for them to be in a real relationship. Seme actually pursued him for 7 years after they met, after they graduated from high school. So if you put that into context they both suffered stupidly because they both couldnt be courageous enough to confess. I guess it is in how the reader views it. If you were to put yourself in their shoes, you would see that the seme indeed pursued him for a suitable amount of time while uke kept sliding away...without saying bye, changing numbers and avoiding seme not once but twice in a span of 15 yrs. That cannot be drawn in a 6 chapter manga. So it imo was okay. Not great, but okay. Because it could have been longer, yes.
To my personal taste, I didn't like how the author put together the plot, the character of Seme seemed too immature, the uke shouldn't have accepted so easily.... I feel like she didn't know how to build an interesting story. ╮(￣▽￣)╭
