The protagonist is a native of a story set in an aristocratic academy. He has four close friends, A, B, C, and D. The five of them are known as the campus F5, and spend every day living the life of spoiled heirs.
One day, the protagonist closes his eyes and opens them again, only to find himself...
At his own grave, ten years later.
Friend A is dressed in a suit. He had been gazing sadly at the sky, but as soon as he sees the protagonist, his CEO-like composure vanishes. He grabs him and asks his name.
The protagonist says his name is XX and that he is eighteen.
Friend A is overjoyed. "You're really not dead! You just transmigrated through time...!"
Only then does the protagonist learn that in this parallel world, he died at eighteen, and ten years have passed since his untimely death. His friends are now twenty-eight.
One by one, they have become major figures in politics, business, and entertainment. The only one who hasn't even started college is the protagonist.
Sigh! Time waits for no one! His friends were once just ordinary guys, but now they're old enough to be his dads!
As it turns out, his friends get into a fight over custody of him.
A, B, and C pull at one another's hair and argue fiercely, before finally setting some rules:
Monday and Tuesday, A is the protagonist's dad; Wednesday and Thursday, B is his dad; Friday and Saturday, C is his dad. On Sunday, the protagonist can freely choose his driftwood.
The protagonist laughs helplessly and asks, "What about D? Doesn't he want to be my dad?"
"Well, about that..." A, B, and C stammer. "D is really unhinged. He's mentally ill and has been crazy for ten years..."
A, B, and C are tight-lipped about D's situation and warn the protagonist not to go looking for him.
The protagonist is very curious. After asking around, he learns that D, once the most inconspicuous and gloomy-tempered member of their friend group, has become an all-powerful big shot in the neighboring city.
He sneaks off to the neighboring city and, after some effort, waits for D outside his company.
A car pulls up at the entrance. Every detail of D's appearance is impossibly handsome, making him the spitting image of a modern-day overpowered hero.
The protagonist: "Hey?"
D says nothing, staring straight at him.
The protagonist walks up admiringly. "Long time no see, bro..."
D parts his thin lips. "Wife."
The protagonist: "????"
