This is the fourth story in the Undone series. This is Jung Hoseok's time to shine. He is taking control of a new project at Stellar Design, and he has decided it's time to take control of his love life as well. He is weary of being alone, and he is ready to move forward in finding love. But, fate has perfect timing in pointing out that control is an illusion. Hobi is forcibly reminded of that when Izabelle Walker appears at his first project meeting. He may have vowed to make a new start in finding love, but no matter how strongly either of them fight it, there is no denying things between these two were left unfinished.
