A story that begins with lies and ends with deep love, about "truth" and "protection".
Yuan hope, who experienced darkness in her childhood and lost everything, changed her name and life as "Ran Xi" due to an unexpected tragedy, and walked into the Ran family, which is full of warmth but also hidden scars. With atonement and gratitude, he carefully guarded the family as an "brother", especially his sister Ran Yue, who was like a little sun.
As time went by, he originally wanted to bring this secret into the dust and spend his life repaying this stolen family love. However, as fate would have it, the boy who should really be called "Ran Xi" - the sunny and cheerful Ivan, unexpectedly reappeared. The silent pull of blood ties made Ivan involuntarily move closer to Ran Yue.
Seeing that the boundaries were about to be broken, the fake "Ran Xi" had to reveal the bloody truth with his own hands, tearing apart the protective cocoon that he had woven with lies for more than ten years. He was ready for trial and ready to leave.
But what followed was the sudden death of her mother, the accusation of her father's collapse, and the sudden outbreak of hereditary schizophrenia latent in Ran Yue's body... The world was distorted in front of Ran Yue's eyes, and auditory hallucinations and delusions engulfed her reality. She can't tell the difference between true and false, and is afraid of everything, including her brother, who she once relied on the most.
As a result, this person who had been living a lie from the beginning became the only truth in her crazy world. He took medicine with her, stayed with her through long nights tortured by hallucinations, and told her over and over again what was true and what was false.
He told the biggest lie, but he also gave her the most unquestionable truth.
"Brother Xixi, since we start as 'family'..."
When heartbeat becomes a contract, when protection becomes instinct, they will eventually understand that some bonds have long transcended blood and names.
"Since we started as 'family,' let's stay family.
