Where will the cards fall for this spicy love triangle? Find out in the finale of this love story that began with two step-siblings falling in love under the same roof!

After getting turned down by the guy she had a crush on for ages, Sakura thought things couldn't get much worse...until she realized that she had been seen! Embarassed, defeated, and exhausted, the only thing keeping her going was that she was about to meet her cute little step-brother...until it turns out that her "cute little brother" was not only a tall, handsome guy in her class, but he was the one who'd seen her get rejected! Now Sakura has to pretend everything is cool, but with an over-protective "little brother" who sees the best in Sakura, and an aloof crush who starts to take an interest, Sakura's high-school life will be anything but easy!

Sakura Nishiyama's had a hard time facing her parents lately, and it might have something to do with her steamy relationship with her smokin'-hot step-brother, Kaede! The two agree to keep it rated PG-13 for now, but will their boundaries survive a night alone in the same room at a hot springs resort?! And now that the whole gang is in their second year of high school, Hatano has his eye on a new classmate... Sakura! Things are heating up in the Nishiyama household as these two stepsiblings fumble to keep their love alive—but will they also be able to keep it a secret?

At last, Kaede has finally come to terms with his feelings for Sakura, and she's ready to admit that her love for her step-brother is anything but familial! Meanwhile, the older Nishiyama has inspired even Hatano to reassess his personality as he tries to improve himself for her... These two step-siblings may (finally!) have fallen in love, but it's clearly not going to be smooth sailing from here on out!

More than ever, Sakura and Kaede are sure they’re in love and have promised to tell their parents about their relationship someday. But when Sakura’s mom collapses from overwork, Kaede agonizes over the decision he knows he must make. Meanwhile, over summer break, Hatano finally confesses his hidden feelings!

Sakura thought she and her new step-brother Kaede were getting along just fine--right until he hits her with a shocking confession: "I can only see you as a girl!" To make matters worse, the school rumor mill has gone into overdrive spinning all kinds of nasty rumors about their (allegedly) scandalous relationship. Hatano has a daring plan to keep Sakura out of the crossfire, but Kaede's not going to like it...

Sakura and Kaede are embarking on the newest chapter of their lives as same-age "siblings" after their parents' remarriage, but there's only one catch―Kaede's so sweet that he sends Sakura's heart into overdrive!
