Tsubomi's Secrets -Sprout-

Tachibana Tsubomi is a fourth grader whose world turns upside down when she sees a couple kissing at the park. The innocent moment stirs something inside her, leaving her heart racing and her mind full of new questions. Back home, a small event—a lost bird—triggers a series of emotional and physical changes that mark the beginning of her journey into growing up.

As Tsubomi navigates these unfamiliar feelings, she learns about love, friendship, and the bittersweet nature of change. Alongside her best friends Reia and Yae, she experiences the awkwardness and wonder of adolescence, from first crushes to the pain of saying goodbye. Each encounter teaches her something new about herself and the world around her.

This collection also includes four additional stories: "One Day Happening," "Boys and Girls," "LOVE・LIKE・COMIC," and "To You I Will Never Meet Again," each exploring the tender, confusing moments of youth.
