Under the Oak Tree - Chapter 20

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.

I reincarnated into a fantasy world. Since I somehow got born again, I resolved myself to live diligently once more. But, putting that aside, my entire village burning up and disappearing when I’m 8-year old f*cking crossed the line. F*cking shit-f*cking crossed the line!

The fake daughter was spoiled by her elder brother and parents, but she, the real daughter, was disgusted to death and scolded as trash, she endured it… But what happened this time? After the rebirth cycle, the eldest brother who hated her the most hugged her and said that he loves her. Is she his only sister? Several other elder brothers sent the most expensive gifts one after another, just begging her to take a second look? This plot is not right?

Brothers:

“Yanyan, do you eat candy? Big Brother bought it for you all over the country and put it in a candy house.”

“Yanyan, do you like this house? The second brother bought dozens of houses for you.”

“Yanyan, the third brother of the playground has been transferred to your name.”

“Yanyan, my brother will take you to debut at C position.”

Gu Yan: “…” (Help! She really wants to do the task in a low-key manner!)
