That’s normal. I think there is no age difference when it comes to reading novels.
Many girls or boys like to read novels, and they range in age from young to old. I probably started reading novels in junior high school, and now that I am almost 30 years old, I still read novels, but it is different. The novels I read during this period were of different types. When you were very young, you might like to read romance novels. Well, but as I grow older, the types of novels I read have changed. Now I prefer to read some news or apocalyptic articles, but the habit of reading novels has not changed. I just read novels intermittently. .
I don’t think there is anything wrong with reading novels. As long as you can control yourself, it doesn’t matter if you read some novels when you are relaxing. And reading novels has nothing to do with age. My father also reads some novels now, which is a relaxing thing in his free time, so it is normal for a 23-year-old girl to still read novels.
Everyone’s way of relaxing is different. Some people like to watch TV series, some like to read novels, and some like to run. As long as you find your own reasonable way, I think it’s all okay. Watch As long as you can control yourself and don't get addicted to novels, there is no harm in it.
As a 23-year-old, you can still watch dramas even if you don’t like reading novels. So, can you say that watching dramas at the age of 23 is not normal? It's not difficult, so it's a hobby.
