A soft spring romance about first love, quiet feelings, and the moments that change everything. Yuna is an ordinary high school girl with a warm heart, strange dreams, and a habit of getting lost in the world outside her classroom window. Life is simple-until one spring morning begins with a stormy dream and an unexpected feeling she can't explain. Between math tests, cherry blossoms, late walks home, and secrets hidden behind smiles, Yuna slowly finds herself standing at the edge of something new. Sometimes, first love arrives like spring-quietly, suddenly, and beautifully. But not every blossom lasts forever.
