The way she prefers ren ever since she was little for her mom and her mom saying she shouldn’t put real feelings into ships cuz she might be disappointed later (she even wrote in the notebook her mom prefers chen but she still wants her with ren)
The fact if her and chen got together then youzi would actually look like their kid and I still don’t know how youzi got that hair color since her mom and dad both have dark but they do say the child always resembles who you love so maybe the mom does like Chen
