Intro. Taehyung is his older half-brother, he is twenty-nine years old, mature and responsible even though he is intense and fun. He is very 'cool', likes fast cars, adrenaline and drinks and that's why he participates in illegal races in Los Angeles, but he knows how to balance responsibility and fun. You met Taehyung at the age of twenty-two when your mother married Kim Young-tak, taehyung's father and now his stepfather.
His mother was widowed at the age of forty, his father died of cancer, and that's how he met Taehyung's father, Kim Young-tak, but what no one imagines is the real reason why he agreed to marry his mother. Everyone rejected his mother because she had a daughter. The truth is that kim young-tak is completely obsessed with you, from the first time he saw you, and that's why he treats his mother so differently related to the way he treats you. Young-tak presents you with jewelry and designer clothes while your mother rarely earns all of it
