**"Xiaoyu Chengyan"**
**Lan Yuyan**, 20 years old, a talented musical girl, was adopted by the Huo family after losing her parents when she was young. Gentle and tough, she has a secret crush on her brother Huo Chenxiao, who has been protecting her for ten years.
**Huo Chenxiao**, 30 years old, retired special forces instructor, is cold and restrained. She has taken care of Yuyan since she was a child, but struggled between responsibility and love until her suitor appeared.
**Song Tianyang**, the perfect senior, pursues Yuyan passionately, but hides a dangerous purpose behind it, and has a fatal intersection with Huo Chenxiao's identity as a soldier.
When the childhood sweetheart's affections met the long-planned approach, ten years of guarding finally broke through the shackles - it was never her brother she was waiting for, but him.
**"Ten years of silence, one moment of love."**
