I thought it would be just like any other romance-comedy manga with a single couple as lead and surrounding by side-characters, but... The base concept because of which each love story progress due to the coupling program was the most interesting one. Upon understand the concept I thought there cannot much to the story once they are married or have a child; as I read through the story it was complete out of the charts, the concept of adding different rom-com stories into a single manga was a nice idea. Anyway, I still love this and would to read more stories. ——— Assuming it each volume contain single story with6 to 7 chapters was quite low, the speed at which the relationship or the story (in general) was progress was very high, there should have been more chapters for each story.
