What Happens When You Marry a Childhood Friend

“Just keep it short and concise.”
“I’ve regressed. So marry me.”
“……Tell me more in detail.”
Calix Faon (23/War Hero). The most promising groom in the Empire. He is currently receiving a crazy proposal from his childhood friend, whom he hasn’t seen in five years.
——–
‘My life is completely ruined.’
Princess Lizbeth Armierosha realized this only after standing in front of the gallows.
“Any last words?”
“I’ll kill you with my own hands, you crazy bastard.”
Lizbeth, whose ruined marriage led to the downfall of her family, died. When she opened her eyes, she somehow returned to the moment right before she was about to get married.
Miraculously given a second chance, Lizbeth decides to become the crazy idiot of the area, determined not to repeat her ruined life this time……
“If neither of us has a lover by the time we turn 21, let’s just marry each other.”
When we were little and didn’t know any better, I made that promise to my childhood friend. So I ended up proposing to him.
“Actually… I’m pregnant with Calix’s child.”
“Ah, Dad’s going to faint! Hey, catch him!”
“Just put the sword down first! Sis! Brother!”
To avoid ending up with a total loser, I became a fire-type filial daughter.
“Your Highness, I will make you the crown prince. But there is a condition.”
“What is that?”
“To completely destroy the first prince.”
To take down the madman who ruined her life, Lizbeth even joined hands with the eccentric prince.
As her plan for a peaceful second life moves steadily forward, her most loyal supporter, her childhood friend, says:
“I just want to give you whatever you want.”
“…”
“Please, let me do that for you, Lizbeth.”
Even when she opens the door and tells him to get out of this crazy mess, he shows no sign of leaving.
