Lets get one thing out of the way, it's a series about a married couple. They get married in the first chapter and they enter their married life. Somehow, this setup gets equated with an amazing rate of relationship progress, where the story skips the awkward will they or won't they. Yet despite that, it's still the series about two milquetoast, awkward teens who struggle with the basic intimacy so much you'd think that they are grade schoolers.
Reading this series is like seeing a beautiful bird stretch out his wings, fly up high and then fly head first into a window and break his neck. It has all elements it needs to success as a romance and chooses to waste them for being just a cutesy slice of life. To elaborate, it's a story about the married life of the two extraordinary people that bends over backwards to keep their relationship from properly developing and to squash the actual interesting parts about their characters. In the 54 chapters I've read, the series somehow manages to actively add elements that seem to serve no purpose other than acting as random roadblocks to ensure that main characters relationship stays at the level of teenage dating, despite them living together. They are much closer to roommates than any married couple.
This series is ultimately a rather mediocre slice of life, made worse by all the wasted potential it has. Yes, I've only read 54 chapters and I'm aware that this series teases some greater secrets. But lets be honest, if a series feels like a boring chore by the chapter 54, it's not worth reading more more of it.
