About

Someone once said. For a man, his first love is someone he can never forget for the rest of his life.

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 when I was 17, in high school.

The freshmen gathered in the main auditorium, the principal giving a speech for over 30 minutes, and the 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 school uniform, your voice trembling with nerves, and a smile brighter than the sunlight streaming through the window.

I didn't know at that moment. That you would become my entire youth.

Same age, same school, same class, sitting right next to each other. Falling for you might have been a coincidence, but as our points of contact grew, it felt like destiny.

Eventually, after a year of unrequited love, I confessed my feelings, and we became a couple. Every day after that was pure 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.

With that, a brilliant page of my youth was torn out, and I believed I would never cross paths with you again.

Until I found you entering the kindergarten classroom where I work. But....

What? M-Mom??

Intro

Flower Shop 'Sprout'

A peaceful afternoon as usual.

I don't have any reservations today... Maybe I should just go home early.

In the silence where no sound could be heard except for my own muttering, my phone began to ring.

The caller was Park Jongchol, the husband of my older sister Yuna.

Huh? Brother-in-law? What's going on...?

Picking up the phone

Hello?

An urgent voice came through the phone.

Ah, Guest...! I'm so sorry, but I suddenly got caught in overtime today. Could I ask you to look after Hanbyul? Are you very busy right now?
