Your typical reincarnation story

Extras

There are many plot holes, so if you're confused, here are some details in case you have any questions.

/ Before Lizabeth, who looks after Hayden? /

- The maid before Lizabeth. The maid only provides him with clothing and food. Hayden needs to change his clothes (he despises it since it's too complex, so he ordered the maid to give him plain clothes instead) and take a bath by himself. (since having someone assist you in taking a bath is strange)

/ Where are Hayden other maids or butlers? /

- Well, the Dominique family doesn't seem to care about him, so they just provided him one maid, the maid before Lizabeth, to reassure "mother."

/ Did Hayden receive any manners lessons or learn about the Dominique family? /

- He did. I just didn't think of it and didn't include it in the story. HAHA

/ Is everyone in the mansion aware that Hayden is fake Wenz? /

- They certainly do. They simply chose not to discuss it since they know they will be executed if they do.

/ If the "siblings" despised Hayden so much, why did they never play pranks on him in the first place? And after he was awakened, they changed their minds? /

- To avoid being despised by "mother," and because they had school, they have no time to harass him.

After the awakening, "father" no longer cares about Hayden, so they take advantage of the opportunity to play pranks on him while they still have time.

/ How come no one has discovered Hayden and Lizabeth's meeting place? (the garden of pink roses)

- It's because Lizabeth has the ability " Enhance detect," which allows her to notice anyone approaching them. If she sees someone, she'll alert Hayden, and the two of them will swiftly hide behind a tree or in the bushes.

/ Is Hayden disturbed by his siblings' prank? /

- Not much, though he finds it irritating at times; nonetheless, because he was older than them in his previous life, he chose to ignore them because he is better than that.

/ What is the Dominique family's job title or occupation? /

Marquess

(Honestly, I have no idea how kingdom rankings operate; I just made this story without knowing how the system works. Lolololol

And I assume the Marquess is in charge of guarding the kingdom's walls; correct me if I'm incorrect; I can't find any reliable information.)

/ Does Hayden always see Lizabeth's system? /

Because systems need sleep, this isn't always possible. He vanishes from Hayden's sight when he is sleeping and reappears if he is awake.

/ Does Lizabeth have any other friends, such as a maid? or a gardener? /

She does have friends, but they are not as close to her as Hayden is. Perhaps she doesn't want to become too involved to people who might get errors.

She doesn't have any maid friends. The people are there doesn't care.

There are more, I think so.
Just ignore them
