After Being Transported into a Book, I Adopted the Villain Chapter 19 Discussion

For me, what I didn’t like was the fact that the age gap of both characters. I don’t have anything against them, but when Chestnut is 18 years old, Shen Yu would be 31. The plot is okay, but the ML could be older when adopted, because a 10 year old being possessive of someone they are close to (especially someone who adopted you) and who is older by 10 years is a tad bit too strange for me.
