I have only read the first story in this manga, so my review is going to be about the first two chapters.
Suzu Mochida is in love with the older son of the Shuichi family, for whom she and her mother work as housekeepers. Shinji, the younger son, does in turn love her. The typical love triangle story.
This story is the perfect example of how far events can be rushed in a story. The first chapter introduces the characters, although we don't really get to know much about them. Suzu is in highschool, and admires the older Nakatsugawa son, Shuichi. The younger brother, Shinji -who is still in middle school- looks jealous, and is always arguing with Suzu.
Then, there is a gap in the story, and the second chapter brings us to a couple of years later. Everything has changed due to an accident sufferd by Shuichi, the older brother.
I really have nothing against the gaps of time in the story "per se"... it emphasizes the change of atmosphere in the house. But there are many things that are left unexplained. Suzu seems to feel guilty for Shuichi's accidents, but we never get to know what happened really, and why Suzu feels so obliged to take care of him, to the extent of not having a life herself. That could have been shown in a flashback, for example. Everything in the story is shown superficially, there is no depth whatsoever, in the characters or in the relationship among them.
The ending is also forced... extremely rushed... I'm not going to tell how the story follows or ends, but the author obviously needed to end it fast. And how do you think it was done? With another gap of time, we jump into the future again. As I said before, jumps in time are ok in a story, but not if you are going to use them to "avoid" telling the story.
The art is ok, but it does not make up for the bad story.
