In the bustling heart of Busan, two boys — Kim Miju and Han Jeong-Joo — have shared everything since birth: their home, their dreams, and even their café. But everything begins to shift the day Lee Jae-Hee crashes into their lives — quite literally.
She's fierce, unpredictable, and running from a life she never chose. When she barges into their café with a mysterious past and flowers in her hand, both boys are thrown into a storm of emotion neither expected. As feelings bloom and hidden histories unravel, the unspoken bond between the two friends is put to the test.
Three hearts. One tangled fate.
Can love grow without destroying what was once unbreakable?
