Something's Wrong! My Green Plum Seems to Be Suffering from Reincarnation!

[Single heroine] [Funny] [No system] [Pure love] [Tsundere] [Mildly ill] My name is Wang Qingyu, as you can see. I have a arrogant and venomous Qingmei, her name is Shen Yunbai, she is a strong person in the space and time system. There is also a mysterious person in my heart, his name is Yu Shen 3, and his tone of voice is very similar to mine. However, my green plum seems not to be normal. She always has some kind of nightmare, even Yu Shen 3 is convinced of it. However, in front of my powerful sequence [004] talent. I don't care what the end of the world is. Yushen 3 tells me that I will become stronger by defeating monsters, so I just have to cut and slash. It's just that my childhood sweetheart is a little too arrogant, and... Seems to have some unknown past?
