I have had a crush on P'Newt since middle school.
But I can only look at him from a distance.
He is too good for me, like the moon upon the sky.
He is currently a medical student and the most popular student at my university...
...and he has never known that I existed.
One day, everything changed.
When I received a message from myself 15 years in the future.
My future self told me that if I don't flirt with P'Newt now, I will regret it.
Because,
When I stopped falling for P'Newt,
When my heart doesn't belong to him anymore,
On the day I was about to marry someone else,
P'Newt will confess that 'he likes me'.
Warning: Both protagonists have advanced flirting skills.
