In this era of rapidly changing information, on both sides of the screen across time zones, Mijin and Mili met by chance through a cross-border chat software. One is a cold programmer who wanders in the world of code, and the other is a freelance photographer who uses his lens to capture the fireworks of the world. They used words to measure the distance of 8,000 kilometers, and in the conversation between morning and dusk, they changed from strangers online to each other's most trusted soul confidants. When longings across borders begin to materialize, and when the cold screen can no longer carry the fiery emotions, what kind of romantic ending will this encounter that started with keyboard tapping have? Let us follow the story of Mi Jin and Mi Li and witness how a heartbeat that grows in time difference blooms into the most gorgeous flower of love.
