Rumbling Hearts

As high school draws to a close, Haruka regrets that her long-held crush on fellow classmate Takayuki will never see fruition. Moved by her friend's devotion, the outgoing Mitsuki decides to take action and arranges for a clandestine meeting. Prompted to action, Haruka confesses her love at long last and the two become a couple. But what should be a dream come true quickly sours, as even the best of intentions cannot stand up to the emotions of the young at heart.

Their problems in the past, life could not be better for the young couple Haruka and Takayuki. But unexpected feelings of jealousy drive Mitsuki to meddle. Working to gain Takayuki's time and attention, Haruka can forgive her friend just about anything. After all, life is good and the future promising. Takayuki has even decided to attend a university, much to Shinij's astonishment. Running late for his date with Haruka, the young man bumps into Mitsuki once again...

Three years have passed since the tragic accident, three years in which Haruka has been in a coma. Takayuki and Mitsuki are in a loveless relationship, lacking in joy and ridden with guilt. Neither followed through with their plans after high school, and their lot in life is not the shining dream they once expected. Takayuki has an abusive, unfulfilling job at a local restaurant and Mitsuki gave up competitive swimming, once her passion. Of their old group, only Shinji has made something of his life.

Things seem to finally be working out for Takayuki and Mitsuki, for the young man has made peace with the past and wants to rededicate himself to the future. But their newfound happiness is thrown to the wind when the unthinkable happens... Haruka has woken up! And she's been asking to see Takayuki. Suffering from anterograde amnesia, Haruka has no sense of the years that have passed and believes they are all still in high school together...

Flashback: It's been a year since the accident and Takayuki is overwhelmed with grief. Mitsuki, believing the accident her fault, has been taking care of him as best she can. Dedicated to his health and well-being, she reaches out to Takayuki in his darkest hour. Confessing her love, Mitsuki tells him how she has kept her feelings locked away all these years, that she didn't want to betray Haruka. But Akane finds out about this recent turn of events in the worst possible way...

Haruka's condition has everyone living out a warped high school daydream, as they are forced to act as if the past three years haven't occurred. For the young girl's sake, Takayuki has vowed to visit her every day at the hospital and continue this facade. Remembering that Haruka was once the most important thing in his life, he wonders if she still is. When Mitsuki attempts to visit Haruka at the hospital, Akane stops her and yells at her for being selfish, chasing her off.
