At six, Emily Lin lost her parents and ended up in an orphanage. She later marries Jacob Zhou, the second son of the Zhou family tied to her family tragedy. After the wedding, they face misunderstandings, both thinking the other still has a "first love." As the story unfolds, the misunderstandings clear, and Jacob pursues her with romantic gestures—fireworks with her name, mock interviews for confessions, and matching watches with sensors. In the end, they find their way back to each other.
