The twins, Aoi and Akane, have been living with their grandparents from their late mother's side and their father. They are now fifth graders and are about to start taking steps towards life while embracing new encounters and new experiences on their own.
Remember Love so Life? Ever read Love so Life? Well this is the after story. It focuses on the twins who are living with there grandmother and father now and have grown up quite a bit. So read this after you finish the main story. The story is enjoyable, it is nice to see how the twins have grown up and how much they learned from Shiharu/Matsunaga and the grandparents & father also. The ending is funny but, just kinda leaves you wanting that last bit finished but, there hasn't been an update since the last. What makes me feel a little less connected to this half of the story is it feels like they downplayed some areas a bit. In example they addressed Aoi's little crush from the original story but, at the same time they downplayed it by having all the characters not even realize it after the wedding for Shiharu/Matsunaga was announced. (Yeah he is a kid but, the little guy has feelings and his attachment to her should be addressed in a way that wouldn't make him feel like it didn't matter.) Either way worth checking out but, read the main story first or else this will be confusing as it doesn't offer any backstory and just dives right into the story.
