I Thought of You as a Brother, But You Had Feelings for Me?

I feel like Li Chongsheng's past timeline + system idea was good, but was it revealed too early? In addition, the male protagonist's personality is slightly unlikable, and the interaction is not very enjoyable? It's just that Nikki Asashi Yang Wei doesn't dare to fuck...

The author is very careless. When the heroine recounted her rebirth experience, her age was seventeen at the beginning and fourteen at the end. She didn't even check for such an obvious problem.

A lot of the plot is nonsense.
