[Youth literature + Campus literature + Reunion after a long separation + Running in both directions] [Lin Ai, a stuttering girl who lives under the shelter of others vs. Cheng Yuanmu, a sunny boy who is the proud son of heaven] Lin Ai, who lost her parents since childhood and has a stuttering disorder, lives under the shelter of others, but Wang Cheng Yuanmu, a child in the compound, falls in love with her. Cheng Yuanmu is a little sun with bright eyes when he smiles, a bright person who is completely different from Lin Ai. First meeting, growing up, falling in love. He was the warmest light in her cold life. A twist of fate, a misfortune, an unintentional mistake in their youth, and a misunderstanding that refused to give in finally caused them to be separated from each other. And when the two people who had been separated for five years reunited at a friend's wedding, would the person she had loved, hated, relied on, and given up on, and finally hugged in her longing every night, chuckle as before, repeating the teasing when they were young, "How many Ais do you have when you call me Ai Ai?"
