This book is also called "Gentle Sister and Her Heartbeat"
Ever since he had memories, Lu Cheng had always been very gentle to her, and Lin Yu had always regarded her as his biological sister. Whenever danger came, Lu Cheng would always rush to protect her immediately.
Ten years have passed, and Lu Cheng still hasn't let Lin Yu understand her feelings and preferences. She just stays by his side silently.
Lu Cheng looked cold and inhumane, with severe mysophobia, but he was extremely gentle towards Lin Yu, making it hard to believe that he was a human being.
The innocent Lin Yu has been independent since childhood and suffers from severe depression, but he seems very optimistic.
