Like father, like son

Ordinary office worker Ryota Nonomiya (Masaharu Fukuyama) ) and his wife Nonomiya Midori (played by Ono Machiko) have been married for many years, and they have a very good relationship. Together, they raise their smart and well-behaved son Nonomiya Keita (played by Ninomiya Keita), and their lives are peaceful and full of happiness. What the three people, who thought their peaceful life would last forever, did not expect was that a phone call from the hospital where Qingduo was born brought this small family into the spotlight. It turns out that Qingduo is not the son of Liang Duo and Midori, but the child of love between Yudai Saiki (played by Lilly Frank) and Yukari (played by Yoko Maki). Is the relationship of getting along day and night precious, or is the bond of blood connection more important? Faced with the consequences of a small misunderstanding many years ago, Liang Duo and Lu didn't know what to do. For Xiongda, Yukari and their non-biological child Ryuharu Saiki (played by Huang Shengxuan), they are also standing at a crossroads in life.
