Won't you take a peek into the lively daily life of the Yozakura family?
Taiyo Asano is a high school student who was in the depths of despair after losing his parents and younger brother in an accident. He was beginning to reclaim his daily life with the encouragement of his classmate and childhood friend, Mutsumi Yozakura. However, one day, the vice principal, Hirakawa, suddenly targeted Taiyo's life. Immediately after, Taiyo was sheltered by Mutsumi and her siblings, who revealed that their family has been in the spy business for generations. Then, to protect Taiyo's life from the eldest brother, Kyoichiro—who is actually Hirakawa—he is asked to marry Mutsumi and join the family. Taiyo decides to marry Mutsumi, partly to protect her from her brother's suffocating obsession. Thus, the curtain rises on the turbulent spy life of Taiyo, the rookie spy and son-in-law of the Yozakura family head. I'm a beginner, so please be kind! I haven't read the manga much and mostly watch the TV show, so it might not be perfectly faithful to the original source material 💦 I'll try my best to stay close to the original though.
