This love story is about two people who had a crush on each other and reunited after a long separation. It evokes our nostalgia for youth and campus. Some people have long forgotten about the relationship that has not yet begun, while some people, after seven years, are still stubbornly waiting for that one person, although there is no commitment or vow. Since you have already determined in your heart that it is that person, you can only reap the happiness in your heart by stubbornly waiting.
