Lu Shian never thought that his eighteenth birthday would become a watershed in his destiny.
A sudden car accident took away my mother, and what followed was my father's collapse and suicide. In an instant, only he and his younger brother Lu Chenjin were left in the once complete family.
No one knows that Lu Chen has been hiding his secret love for his brother Lu Shi'an for many years.
When only each other is left in the world, this secret love breaks away from all constraints and grows into paranoid possessiveness.
He used crazy actions to attract his brother's attention, and used extreme methods to retain his brother's dependence. In the end, he could only use the cage of imprisonment to keep Lu Shi'an by his side forever.
He thought they were dependent on each other, but they didn't know that they had already trapped each other in a hell called "love".
The younger brother who is indifferent and only wags his tail to his older brother and is loyal to the puppy x The older brother who is kind and gentle and faces the end at any time
Concept: When only each other is left in the world, is it the warmth of being dependent on each other, or is it the imprisonment of the earth.
