It's basically like every Isekai story, the original soul of characters are either dead or gone to be reborn somewhere else.
In this one since its a story our mc wrote she just slipped Weiin in the 3rd prince (〜 ̄△ ̄)〜 and no side note of the original since it basically never happened (the story began when Weiin became a prince in another world she created)

oh yeah huh.. with the world being her story it's not unlikely the guy who also 'transmigrated' is from a different place from hers aka non-existant lol.
Even if the brothers never had a decent sibling relationship, rightfully pissed if some mysterious a-hole possessed your family member and decided to show you up as the "better brother"
We all have student loans, we all can't find a job that we want
