In the Kim mansion, power is inherited, but peace is impossible.
Two families live under the same roof, bound by blood yet divided by ambition. Riku Maeda, the only son of the Maeda chairman, raises his gifted son under ruthless standards while navigating a volatile marriage with Kim Daeyoung, heir of the KS Group. Their constant clashes with Sion and his husband Yushi ignite endless tension, with every meal turning into a battlefield and every success fueling envy.
Between scheming parents, a doting yet manipulative grandfather, and children crushed beneath impossible expectations, the mansion becomes a stage for obsession, betrayal, and rivalry. Talented Sakuya shines under pressure, while gentle Ryo is punished for failing to measure up, mirroring the very struggle between their fathers.
In a world where love is conditional and family is a weapon, every relationship is a war, and survival means choosing between loyalty and freedom.
Jaehee can't stand Riku-and the feeling is very mutual. He's arrogant, cold, and always seems one step ahead, whether it's in class, sports, or just getting under Jaehee's skin. Their rivalry is legendary, fueled by years of eye rolls, sarcastic jabs, and stolen victories.
But when a group project forces them to spend more time together, things start to shift. The insults get softer, the tension feels... different, and Jaehee begins to question if all that hate was really something else in disguise.
Because maybe-just maybe-what he thought was anger...
was actually something much more dangerous: feelings.
He was supposed to hate him. Almost.
