Yamamoto-sensei really knows how to start a story interesting... and then she stretches it out and starts making endless chapters of nothing, and then always introduces a second or even a third couple and redirects the attention away from the main couple and any possible plot, she also starts making extra and unnecessary chapters.
I don't know, I feel her mangas are way too long, or better say, she doesn't know how to handle long mangas, she should end them earlier rather than later, and have some faster character development so the story moves. I don't know, I always lose interest at some point.
