An accidental loss of glasses caused common law student Jiang Jian and military theory major Fu Ming to meet at Jiangcheng University. The silent understanding in the library, the late-night conversations about dreams on the playground, and the young feelings quietly growing in daily interactions. However, the family background gap is like a gap between the two. Fu Ming's father's strong obstruction and the strong intervention of his childhood sweetheart make this relationship full of thorns.
Facing pressure from Fu's father about his future, Jian Jian reluctantly broke up with him; Fu Ming joined the military camp with a heart full of pain, and during high-intensity training and dangerous missions, he wrote his longings into letters that could not be sent. Simplicity turns love into motivation for learning, from being unknown to becoming a well-known lawyer in a top law firm.
Over the past five years, they have been struggling and shining in their respective fields. After retiring from the army, Fu Ming accidentally learned the truth and reunited with Jian Jian downstairs of the law firm. When the misunderstanding was resolved, the two people, who had been separated and waited, finally entered the marriage hall in the cherry blossom season, ushered in the birth of twins, and turned the sadomasochism into the sweetest happiness in the years.
