“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?
