Welcome: A New Journey Begins

The hedonistic billionaire playboy Kim Taehyung has always followed his own path. What matters to him most is whatever brings him the greatest pleasure, regardless of the impact it may have on others. The discovery that he is the father of a one-month-old child comes as a surprise, even though he never planned to settle down.

Unfortunate timing for Taehyung, who had just been named CEO of his father's company. His parents, concerned about their public image and the company's reputation, forced him into an arranged marriage against his will.

Kim Seokjin, a student trying to figure out what he wants to do with his life, is thrown into an unexpected arranged marriage with Kim Taehyung and becomes a stepparent to Taehyung's child.
