Royal Family

Kang Jihyuk was the eldest grandson of Taesung, South Korea's largest conglomerate. He should have inherited everything Taesung had to offer, but due to someone's conspiracy, he lost his parents and was abandoned in an orphanage. Twenty years later, he returns to Taesung under the name "Seo Jihyuk"... and his revenge begins. (Source: Naver, translated)
