“Are you planning to jump?”
“…What?”
“I’d really prefer it if you chose to live. Because if you die, I’ll follow you right after.”

That’s how Jihoon met Seo Haewon—on a bridge, drunk and at his lowest.
He thought it was just a one-night mistake, but Haewon says he’s known Jihoon for a very long time.
And somehow, without hesitation, he reaches out a hand just as Jihoon stands at the edge of a life that’s gone completely dark.

“What I want… isn’t your gratitude, Jihoon.”
“Wait, are you saying… you want to date me?”
“Dating’s not enough. There’s no way I’d be satisfied with just that.
Love me—the way I love you.”

Before Jihoon can even process this intense confession from a stranger, Haewon adds with a cheerful grin:

“How about we take this slow, maybe five steps total?”
“…Steps?”
“Step 1 is sex. Step 2 is kissing.”

They’ve already had sex and kissed. So… what’s left in steps 3, 4, and 5?
And who is Seo Haewon, really?
