Live chat is a way of connecting with people -- there she's called "Yuna" (Horikita Maki). Exchanging words with people is her job. Two years ago, there was an incident. Now she's lonely, doesn't leave her apartment, and works at home. She can't normally talk to people. Live chat is the only way to interact with others. This virtual world is her everything. And then her life changes...

Nakagawa Kana has worked hard all her life to become a successful competitive swimmer. Under her father's pressure, she is aiming to become a representative at the next big swimming competition for her school. Life is much like a swimming race, every second counts, and to Kana doing anything else other than being the best is pointless. One day, she gets caught in one of her shoplifting acts – something she does only for the thrill rather than for the product – by her childhood friend, Daisuke. Without much consideration, she pulls him to a nearby hotel where they spend the night together. However, Kana does not expect what happens afterwards would affect everything she has worked for.
