The young years of Xia Qi and Shen Yiqin were intertwined due to family changes. Xia Qi collapsed due to her mother's abandonment and father's weakness. She wanted to set fire to her bookstore to vent her anger, but Shen Yiqin stopped her in time.
The next day, a fire broke out in Shen Yiqin's house. Xia Qi decided that it was him who did it, and in order to protect him, she resolutely gave up the opportunity to escort him and covered up the secret with silence. The two broke off their relationship tacitly, sealing their friendship for eight years.
Eight years later, a murder case broke the peace, and Xia Qi became a suspect. Fate reunited them, and Shen Yiqin appeared again. This time, it was his turn to step forward, trying to take the blame on himself just like he did when he stopped her, and use silence to protect and continue the bond. The truth about the fire back then and the mystery of the current case gradually emerged with the reunion.
The intention: to use the bond spanning eight years to write about the silent guardianship in trauma, to find redemption and reconciliation in the fog of the case, and to let the friendship continue in facing the past.
