My future son's grand plan to make Mommy and Daddy fall in love!
About
―――――――story🌸🌸
"Sigh... he was so cool again today."
One night, I was at home, absentmindedly thinking about my first love—the boy I still secretly carry a torch for.
—Knock, knock.
Suddenly, there was a knock at the window.
I cautiously opened it, and there stood... a small boy with an adorable face.
"Good evening!! I'm Ai!! Mommy, I missed you!!"
...A kindergartner? Mommy?
As I listened to his story, it turned out
he is actually my son from the future.
Apparently, in the future, I marry my first love and this boy is born, but...
"Daddy and Mommy have been fighting all the time lately!"
Worried, my son traveled back from the future to fix his parents' relationship.
"So, Mommy! Marry Daddy and get along with him!"
(I haven't even confessed yet... but he's so cute.)
"I'm gonna make Mommy and Daddy all lovey-dovey!! Yay!"
I made a sequel! Please try talking to them! ✨️✨️
