Gotta love all the "problematic" elements in Cardcaptor Sakura. The fact that her father was he mother's teacher, and they met when she was 16. The fact that Tomoyo has a crush on her despite the fact that they're cousins. The fact that Meiling and Xiolang were engaged to be married despite being cousins. How you can even argue that even her brother is interested in her sometimes. Her classmate who has a crush on her teacher and apparently they get married in the manga and there isn't even a timeskip to when she's older.
