"I'm just like at the bottom of the ocean, in the darkness, hiding from reality. Away from my friends.

Away from..."

Yuki Mizushima is just a regular teenage girl that once had five childhood friends in Iwatobi town, but had to move to Tokyo. It was hard for her. Just in a few years, she moves back to Iwatobi, and now attends to Iwatobi high school. At her first day, she meets four familiar people she met before, and realizes that it was four of her childhood friends. As the day goes by, it ends with a memory from her daunting past that happened back at Tokyo, which scared Yuki for the rest of her life, and eventually became her biggest fear.

Meanwhile, she has feelings for one of her childhood friends. Back then, they were always hanging out with each and always there for each other, but what her friend does is Yuki's fear she cannot escape from.

What was her fear? What happened during Tokyo? Will her friends ever be successful to get her over her fear? Can Yuki escape from her daunting past? What does this childhood friend do that scares Yuki?
