Love the North and Huainan

Destined+younger brother+girl is not a virgin+only love [Objective and rational designers vs. Stable, poor college students seeking to make a living] [Age difference × 3] [No accident] [True diagnosis] Note: [BE] [Non-male protagonist] [Short-lived] That boy looked exactly like her when she was young. Stubborn, persistent, and believes that when you are young, you should follow your heart. It was an unintentional move, on that snowy day. She sent a young man back as a student, The young man was young and calm, very similar to her in the past. One trip to each other, two meals, and three thousand gossips. That's how the story would have ended. The young man came over. He was loyal, clean and pure. He likes orchids, as pure as orchids. She once asked him, "Can you please stop fooling around?" The young man said calmly, "I know what I want to do." Entangle, pull, give in, approach, compromise. The moon waxes and wanes, and people have joys and sorrows. The fifteenth day of the month is round and bright. He got what he wanted, love was finally complete, and he swallowed. "I love you." She was calm and calm and just said "I know." They are all crying, why are they crying? Why do we cry for good things? Probably even if you get it, it is destined to end in tragedy. He gained a lot, except her.
