Romance! A crazy, overprotective brother! And...spies?!

Taiyo Asano has been on his own ever since his parents died. The only one who seems to care for him is his childhood friend and classmate, Mutsumi Yozakura. But Mutsumi has a secret—she is the head of a family of spies!

As his body is disintegrating from Kyoichiro’s Blooming, Momo entrusts the plan he and Rei initiated to protect the family to Taiyo. But then a man calling himself Asa appears and takes Momo’s body and Rei’s heart! The Yozakuras now face a dangerous new foe despite rescuing their brainwashed siblings… That doesn’t stop them from enjoying a little downtime first, though!
