Crossing the Crowd to Chase Love - Chapter 52

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

PS. Cover not mine, I just found it on google.

I fell in love. Her name was Shirasaka Yukino. I could only look at her from a distance. However one day I heard that she already had a boyfriend. Even if I love her, I can’t have her. The devil sent me an invitation. I can make her mine!

After dying in the world of One Piece, he was reincarnated once again this time as Neji Hyuga. But fate was no kinder here. With his father dead and the cursed Caged Bird Seal looming over him, for his survival he made a ruthless decision....

System: “Host, let’s brush the protagonist’s favorability!”
System: “Host, stop! Stop for a while! You’re walking crooked! That’s not the case!”
Yu Shisan: “As long as it’s goodwill, it’s fine.”
System: “But the protagonist… you’ve all been bent by you!!!”

Yu Shisan comes with a halo of pretense, and his favorability level rises. The style of painting is flat and cool, each world is short, and the sixth or seventh chapters are over.
There are all kinds of plots in the campus ghost palace fight

ps:

1. The female protagonist brushes the favorability of the protagonist in the original world, love, family and friendship are all favorability degrees

2. Do not like x Some worlds are okay, some are not well written, if you see a world you don’t like, just look at another one.

I was very talkative when I wrote this… This is the first pit… The style of writing two years ago

High school student level…considerate…
Thank you all for your support and encouragement! Love you guys!
