After losing her husband to death following a troubled marriage, a woman unexpectedly travels back to the moment before their first meeting, allowing them to reconnect and rekindle their romance.

In an abandoned Tokyo overrun by bubbles and gravitational abnormalities, one gifted young man has a fateful meeting with a mysterious girl.

Yuna and Akari are two high school girls with very different views on love: Yuna dreams about romance through rose-coloured glasses, while Akari is down-to-earth and practical. Meanwhile, high school boys Kazuomi and Rio also have different views on love: Kazuomi is an airhead who can't grasp the concept of love, while Rio grabs onto any confession as an opportunity—so long as the girl looks cute. Will these four classmates end up leading a youthful romance that meets their expectations?
