Koiti Mikage, the world's wealthiest man, had spent years concealing his identity while working as a cashier to raise his son, Kazuma. Unexpectedly, Kazuma ended up marrying Yuki Hanyo. The Hanyo family was domineering and overbearing, so Kazuma tried to keep the wedding from Koichi, yet Koichi showed up uninvited. At the wedding, Kazuma was belittled at every turn, prompting Koiti to step in and defend Kazuma. Despite initial mockery, Koiti just responded by presenting extravagant gifts. But when faced with persistent provocations, Koiti no longer held back. At that moment, his powerful and influential goddaughter burst in, declaring her desire to marry into the Mikage family, which sent shockwaves through the crowd.
