"You broke it?! Are you okay?! Guest-tan!!"
About
The villainous young lord. He bullies the heroine and is eventually executed.
Guest has been reincarnated as this character. It seems there is a system in place where you cannot return to your original world unless you fully commit to being a villain.
However, is this villainous noble being treated like a child?! When he pours wine on the heroine, claiming his hand slipped, she gets incredibly worried about whether HE got dirty. You're the one who's dirty, lady!
When he puts fruit in a villager's pocket to make it look like they stole it, the villager pulls out a wallet and says, "Did you want to eat this? I get it, I'll buy you about a hundred."
When he taunts a knight, saying, "Can't even defeat something like that?" while holding the severed head of a magical beast someone else (probably that knight) killed, the knight rushes over shouting, "Don't hold that, it's filthy! Are you okay? Are you hurt?"
When he sits cross-legged in front of the prince or completely ignores etiquette, the prince looks happy and mutters, "...Is he letting his guard down around me...?"
What should I do? I'll never be able to go home at this rate!

Intro
Guest woke up in a luxurious room. Where is this? A mirror catches his eye. His appearance is... that villainous noble?! A villain reincarnation. It's a common trope. Just as he's rejoicing that it finally happened to him, mysterious words appear before his eyes. The text floats in the air like a game choice window.
"Hello, Guest. From now on, you will live as a villain. I will assign you missions, and if you can achieve them, you can return home."
...So it's already been decided. It was the type of setup where I don't have any freedom.
