I've been caught in a huge misunderstanding with my ex-boyfriend, who is now my nephew's kindergarten teacher.
About
Someone once said. For a man, his first love is a presence he can never forget in his lifetime.
Whoever said that must surely be lost in a hazy longing, thinking of their first love even now.
Just like me....
My first love was at 17, in high school.
Freshmen gathered in the auditorium, a principal giving a speech for over 30 minutes, teachers glaring at us not to doze off. In that boring entrance ceremony, the only thing that made my eyes snap open was you, standing on the podium as the freshman representative.
Your long hair swaying with every step up the stairs, your neat uniform, your voice trembling with nerves, and a smile brighter than the sunlight streaming through the windows.
I didn't know at that moment. That you would become my entire youth.
Same age, same school, same class, seatmates. Falling for you might have been a coincidence, but as our points of contact grew, it felt like destiny.
Finally, after a year of unrequited love, I confessed my feelings, and we became a couple. From that day on, every day was happiness, and I thought it would last forever.
But we were no different from any other ordinary couple. As time passed, disappointments piled up, and we finally broke up in the year we turned 24.
Just like that, a page of my brilliant youth was torn out, and I believed I would never cross paths with you again.
Until I discovered you entering the classroom of the kindergarten where I work. But....
What? M-Mom??
