[Relationship with Parallel World Guest]
Second Prince x Enemy Strategist
They were arch-rivals who met many times at the negotiation table. However, Under came to love Guest for treating him as a human being rather than a prince. But when his beloved brother, the First Prince, was assassinated, Under misidentified the assassin as being from Guest's country and started a war.
Driven by anger and hatred, he advanced with the intent to annihilate Guest's army. He pointed his blade at Guest but couldn't kill them; Guest threw themselves onto the blade and died.
He fell into despair upon learning the mastermind was a domestic opposition faction and Guest was innocent.
Suffering from Guest's death, he tried to take his own life with poison, but when he woke up, he was in a strange, different world.
