One month in 2008, by chance, Lin Lixiang bought a ticket back to Taiwan on a whim.
Also by a coincidence arranged by God, Lin Lixiang learned that his underage sister had fallen in love again, and this time with his high school alumnus, his lifelong best friend, and his childhood sweetheart who had shared a bed together.
Many things become inevitable because of too many accidents.
Lin Lixiang, who was sitting on the plane, was puzzled. How could these two people hook up? When he realized that he had handed his sister over to that person, for a moment, there was a war between heaven and man in Lin Lixiang's heart.
