When I was five years old, I held my brother's little hand tightly and watched him being dragged into the orphanage, while I was forcefully dragged onto the plane by strangers - that was the last time I saw the mole on his neck clearly. This mole has become an obsession engraved in my bones and blood, supporting me through half my life of wandering and searching for him for fifteen years. Life in Liuhe Village was full of misery. I had a crazy mother and an abandoned father. I managed to survive with my infant brother in hand, but fate insisted on killing them all: my mother was completely crazy and bullied, and my brother and I were sent to an orphanage. An inter-country adoption separated us forever. In ten years in a foreign country, I went from being an orphan living in a foreign country to becoming an upstart with a strong business presence. The love of my adoptive parents and my smooth career couldn't fill the void in my heart. My dreams at midnight were filled with my brother's cries and my regret for not being able to protect him. I gave up the comfortable life abroad and returned to China, building a company while looking for my younger brother. I encountered scammers and others who tried to persuade me to quit. Even my father, who had been missing for half his life, wanted to make up for it with remorse. I collapsed countless times but never dared to stop. Until I was in a remote mental hospital, and I saw that crazy boy. The mole on his neck was exactly the same as in my memory. When the DNA test results came out, I cried until I lost all my strength: Lin Nian'an, I finally found you. I devoted everything I had to treating my brother's illness and guarded him every step of the way. The gentle Li Jun accompanied me through the darkest moments, and my belated father tried his best to make up for it. But I know that only when my brother recovers and my sister and brother depend on each other, my half-life wandering can be considered a destination.
