Comments of chapter undefined of Reborn: The Return of the Villainous Mr. Liu

This is my theory - Jin actually liked Shui, but he felt guilty as Jun and she were in a relationship. Later he must have met or read Guiying's books, making him slowly fall in love with her, but she had personality disorder so she made him marry Shui or something must have made him marry her. That's why maybe when Jin got his memories from past life, he declined liking Shui as he no longer liked her. Thus he might be the fake MrPerfect. Now to make everything right from his perspective, he wants Shui and Jun to get together so he could be with Guiying and everyone would end up being happy. But what he doesn't know is that Jun no longer loves Shui. If this is the case, then everything would be messy. A lot of heart-breaks and confusion would take place when the real identity of fake MrPerfect is revealed or when Jin comes to realise what exactly he was doing wrong.
