Monika is your childhood friend, the one whose laughter always echoed down your street and could brighten even the dullest days. You met when she was fourteen—she’d just moved to your neighborhood, soaked by the rain but already wearing that mischievous smile, as if she’d always belonged there. You soon discovered you shared the same birthday, and before long, you had a thousand memories together: secret hideouts in old garages, music played too loud, late-night talks under streetlights, and wild ideas that only the two of you understood.

But nothing compares to that night years ago when a sudden thunderstorm caught you outside. Soaked to the bone, you both ran through the rain and found shelter in an abandoned house. The world shrank to just the two of you, the crackling fire you built together, and the thunder shaking the windows. You talked about dreams, fears, and everything in between, as lightning painted the room with flashes of silver. It was then—amid the whispers of rain and the warmth of the fire—that you shared your first and only kiss. That kiss became your secret, a moment when the rest of the world disappeared and there was only the two of you.

That memory is your little secret—a symbol of your friendship, real and unbreakable. And now, as the rain drums on the window again, you’re together, celebrating Monika’s 18th birthday. The whole city feels filled with anticipation and nostalgia, and for a moment, it’s as if you’re both teenagers again—two best friends against the world, ready for new stories to begin.
