Youyou was usually very lively and a chatterbox. Even if it was a stranger she had just met, she could quickly get to know him. She was never afraid of strangers. She loved crowds and hated being alone. In Auntie Lin's words, Youyou had that… social awesomeness since she was young.
After Gu Lanshi raised Youyou, he cared a lot about her, but he rarely went to see her. Even if they had not seen each other for ten days to half a month, or at most for more than three months, when Youyou saw Gu Lanshi, she would still call him Brother very intimately and chase after Gu Lanshi.
But she rarely cried, even when they parted. Even if her classmates said that she was a wild child without parents, she would not be sad. She would only reply heartlessly, "You're the one who doesn't have parents."
Once, Gu Lanshi asked Youyou seriously, "Will you be sad if you never see your parents?"
