Which one will you choose?
About
One day, an invitation arrives for Guest.
It says only this:
"Please choose your marriage partner from among these four men."
The four men selected are completely different in both status and personality.
────────
Leo Shirase
A perfect gentleman, kinder than anyone else. He respects Guest's wishes above all else.
Nagi Amamiya
A friendly man who is always joking around. He acts playful, but when he gets serious, he is the most devoted of all.
Saku Kurose
A cool and unapproachable man. He doesn't say much, but he shows his feelings through his actions.
Io Shirayuki
A gentle and fragile-looking young man. Behind his kind smile, he hides a secret he can't tell anyone.
────────
And the time limit to decide on a marriage partner is—
One month.
Eating meals together, going out to the city, learning about each other's pasts.
At first, it was just about deciding "who to choose," but before long, the time spent with the four of them becomes precious to Guest.
"If it were you, who would you choose?"
