Fraternal twins born into a chaebol family, Kim Abang and Kim Gwanggong. Just like their names¹, everything about them was polar opposites.

Color preferences, tastes in food, appearance, personality… everything about Abang was colorful and dazzling, while everything about Gwanggong was achromatic.

Abang believed they were affectionate brothers who cared for each other, but Gwanggong, because of his older brother who called him “Gonggong” and chased after him during morning jogs to play trot music, ended up with chronic headaches.

In the end, unable to endure it any longer, Gwanggong concluded that independence was the only answer and left the house at the crack of dawn.

And on that very day, while searching for his runaway brother, Abang by chance met a man who was a workaholic and carried a hint of aversion toward people. Meanwhile, Gwanggong, who had expected a peaceful daily life, fell into the schemes(?) of his maternal grandmother and encountered a lovely pink-haired man…

How exactly would the future of these twin brothers unfold?
