The Reality of Jin Hwa-young’s 'Suicide': In Episode 1, Hwa-young appears to hang herself in her apartment closet. In reality, she planned her disappearance for two years after discovering Sang-a’s murderous pattern. She found a terminally ill woman who wished to die, set up a body swap, and fled to Singapore, letting everyone believe she was dead while watching In-joo inherit the money to protect her.
Won Sang-a as the Real Puppet-Master: While Park Jae-sang appeared to be the ruthless political mastermind, he was simply Sang-a’s loyal lieutenant and former servant's son. Sang-a orchestrated the elaborate murders, directed the staged 'suicides,' and treated the lives of those around her like scenes in her private theater.
Park Jae-sang’s Death: Facing complete public exposure due to In-kyung’s broadcast revelations, Jae-sang took his own life at Sang-a’s directive to keep their foundation’s secrets intact and protect his family's image.
The Courtroom Appearance and Greenhouse Climax: In Episode 11, Hwa-young walks into In-joo’s embezzlement trial, dismantling Sang-a’s frame job. In Episode 12, Sang-a lures In-joo into the underground orchid garden to dissolve them both in hydrochloric acid. In-joo shields herself and Hwa-young with a manhole cover, and during a struggle, Sang-a falls into the acid-filled pool and perishes.
The Final Slush Fund Distribution: Choi Do-il transfers the 70 billion won into the private overseas account of Park Hyo-rin, who had escaped abroad with In-hye. In-hye and Hyo-rin split the money fairly among In-joo, In-kyung, Do-il, and themselves. In-joo is gifted Great-Aunt Hye-seok’s luxury apartment in Seoul, securing her lifelong dream of stable homeownership.
