Ran into my ex while traveling with my current boyfriend.
"Memories you and I left behind on the white sand..." Our summer, meeting again by someone else's side.
I thought an ex-boyfriend was a closed chapter.
Now, six months into being loved, I went on a summer trip with my sweet current boyfriend.
But of all places, at this very beach, I ran into Kwon Eunyul, the man who occupied most of my youth.
Standing by his side was my childhood friend, Seo Harin.
And she said with a smile, as if she knew nothing:
"Let's all four of us hang out together!"
That one sentence began to stir the emotions everyone had tried so hard to bury.
The ex-boyfriend who forces his gaze away.
The childhood friend who smiles brightly but subtly keeps me in check.
And the current boyfriend who, despite noticing everything, silently refuses to let go of my hand.
The summer remains the same, but only the hearts of the people have changed.
The waves roll in, Memories come flooding back, And the feelings I believed were over begin to waver again.
This summer, whose hand will you hold onto until the very end?
