Mayu audaciously asks Kaoru on a date in front of the entire household. Since his engagement to Aoi is still a secret, he fails to decline. Stunningly dressed but ill-prepared, Mayu reveals her one passion to Kaoru in response to his sensitive request.

Mysterious noises spook the mansion’s residents. Taeko, the authority on ghostly matters, leads the attempted exorcism through a dusty attic. Mayu finds it prudent to sneak into Kaoru’s bed for a cuddle, resulting in a heap of hilarious frights.

A hard-earned get-away calls Kaoru and his flock to a resort in the mountains, where Mayu just happens to be nearby at her family’s vacation home. A game much like truth or dare gets interesting—especially when Aoi is asked some personal questions.

Kaoru’s got to pull an all-nighter to finish a big report, or else he’ll be writing more all summer long. Graduate studies are demanding, but so are four admiring girls all trying to ease his stress.

Chika and her two friends are the only known members of their high school’s swim club. The district’s swimming competition is approaching, but Chizuru still can’t finish a lap. Tina offers to coach them and splashes in some trademark mischief.

Kaoru’s graduate professor rewards him for his dutiful work with two tickets for a cruise. After receiving Miyabi’s blessing, Kaoru and Aoi cherish the time alone without the usual worrying over possible interruption.

The whole gang, Chika’s friends, and yes, Mayu too, enjoy the luxuries of a spa resort. Taeko takes a break with a few drinks, Miyabi gets a massage, and Tina and Aoi try out a private bath—the same one Kaoru got in just a few minutes before!

Aoi confronts her mother, who personally appears to claim her and is impressed by her commitment. Aoi and Kaoru are sent to live at the Sakuraba summer home, but under Miyabi’s thumb and must keep their union a secret!

The game is on when Miyabi volunteers to teach Chika how to play tennis. Kaoru and the rest of the girls come along for some friendly matches. Kaoru tries his best to focus in between glances at Aoi’s impressive form in her endearing tennis attire.

After Aoi confesses her lifelong dream, Kaoru still can’t bring himself to resume his role as the Hanabishi heir. Despite Kaoru’s reluctance, Aoi insists on serving Kaoru and hints of romance fill the air.

Chika’s high school friends Chizuru and Natsuki get the impression that Kaoru’s her live-in boyfriend—she relishes the thought and replies to inquiries vaguely. The girls’ insist on satisfaction, resulting in a raucous and embarrassing house visit!

While Taeko ponders her feelings for Kaoru, nosy cousin Chika tricks them both into some embarrassing encounters. Another chance alone with her crush only highlights Taeko’s clumsiness.

It’s been two eventful years since that fateful day Aoi and Kaoru were reunited. He takes a break from his graduate classes, and the clandestine lovebirds celebrate their anniversary filled with memories and fantasies of the future.

Aoi and Kaoru take a trip down memory lane on a shopping trip through Tokyo.

Fearful yet resolute, Kaoru and Aoi desperately confront her headstrong father to convince him to accept Kaoru as his future son-in-law. Should they fail, Aoi will be forced to marry someone else and lose her true love forever.

Aoi’s birthday falls on the Star Festival, the most romantic holiday of the year. To afford the perfect gift Kaoru secretly works all week, but Aoi’s worried he’s avoiding her. Both are in for a surprise.
