Four high schoolers discover that the butterflies in their chests aren't just nerves. When a chance encounter at school pulls them into each other's orbits, they begin to understand what it means to feel something real for the first time. There's Minhee, caught between what his heart wants and what his future demands. There's Jiwon, learning that vulnerability can be strength. There's Sora, whose walls come down slowly but surely. And there's Tae, the one who asks the questions no one else dares to speak aloud. Love here isn't simple. It's messy and awkward and occasionally ridiculous. It makes them braver and more terrified in equal measure. Over twelve episodes, these four navigate crushes, jealousy, confession scenes, and the genuine fear that comes with admitting you care about someone. Spring feels eternal when you're this young, but the seasons change. Their challenge isn't just falling in love. It's figuring out how to stay. This is for anyone who remembers what it felt like when everything mattered impossibly more.
