Events that happen to one character also affects those around them, causing all involved parties to face themselves along with their circumstances.
Aspiring musician Nana Osaki is well-versed in scrabbling her way back up after life kicks her in the teeth.
But Osaki has never experienced the warmth of family that Komatsu exudes, so while they seem as different as the symbols for Yin and Yang, they also balance each other.
Together they meet up with Junko and Kyosuke, where they all decide to visit the beach for vacation.
Nana had at least 1 relationship in the past.
Fate brings these two together as roommates and the narrative unfolds to reveal the tender anatomy of relationships and the power they have to shape people and their respective worlds — for better or for worse.
