Cheng Fu and Cheng Yu have been together for eighteen years. From childhood to adulthood, everyone, including themselves, believed that they were brothers and sisters connected by blood.
As we get along day after day, Cheng Yu's dependence slowly turns into a secret crush. She hid her thoughts in jokes, temptations and restraints. She was obviously full of enthusiasm, but she was tightly trapped by the invisible wall of "blood brothers and sisters". She did not dare to completely cross the line and could only lie dormant in silence.
Cheng Fu was also bound by inherent cognition. When he heard his sister's out-of-bounds confession and saw her body approaching on the verge of impulse, he was left confused, panicked and at a loss. While he abides by his duty as an elder brother, he is trapped in this unsolvable ethical dilemma and has no time to face the emotions around him. For many years, all his obsessions have been pinned on his old man Xu Yao.
The story runs in two parallel lines: in reality, the two of them coexist peacefully on the surface, but their inner thoughts are pulling at each other; the memory line gradually unfolds the group portraits of junior high school teenagers, confused high school romance, and college years full of regrets, completely piecing together the growth trajectory of Cheng Fang who does not know how to love.
A dinner party with old friends brings to light all the old regrets; and at the end of the book, a shocking truth that has been buried for more than ten years is slowly revealed - the two are not related by blood at all. Cheng Yu is the orphan of his parents' best friend, and his well-intentioned concealment at the time created a long and futile misunderstanding.
But time has passed, and although the shackles of identity have disappeared out of thin air, the two have already reached a divergent intersection amid years of estrangement and regret.
All kinds of fetters, meeting each other, will never meet again.
Purpose: To tell the story of regrets and restraint in youth growth, to explore self-awareness and reconciliation in intimate relationships, to point out that time and misunderstandings often lead to irreparable misses, and to teach people to calmly accept the unfulfilling destiny in life.
