Cen Xinglan is not a qualified shadow guard, because she has a secret, that is, she has been dreaming about her master for three consecutive days - the owner of Haoyue Villa, Gu Yuanchen, who is known as the cold-faced King of Hell in the world.
Cen Xinglan knew that she had fallen in love and had broken the rules of the shadow guard. Fortunately, she just had unrequited love. If she had done anything extraordinary, she thought she had not been discovered by Gu Yuanchen.
Until an accident, Gu Yuanchen fell into a trap and was seriously injured. However, after recovering from the injury, Gu Yuanchen's mind regressed to the age of fifteen or sixteen.
Although the cold-faced King of Hell was not a good person when he was a boy, Cen Xinglan couldn't bear the stubbornness and vigilance in his eyes that were unique to a boy.
So Cen Xinglan, as the only shadow guard who knew the truth, became the boy's only straw.
Outside, the boy tries hard to maintain his domineering attitude as the cold-faced King of Hell, but inside, the boy who is at a loss gradually relies on the shadow guard who always seems distant.
When Gu Yuanchen woke up, he found that once someone walked into his heart, he could never get out again.
Purpose: perseverance and happiness
