Really loved it. The manga tells 4 stories in parallel, all happening in the same universe so that they somewhat overlap and interact with each other, but only marginally. (This means that you can also easily read one story after another!) The basic premise of each story is the same; a romantic story between two people who knew each other in their past lives, but each with their own spin to it. All of them are very light-hearted though, and purely focused on the development of the respective characters with barely any focus on other characters at all. TL;DR: If you like light-hearted, cute romance, go for it.
