Yamada sees Kase running and something shifts, suddenly the careful girl tending flowers realizes she's the one being grown into something new. The anime doesn't pretend this needs conflict or revelation; it just lets two people figure out what it means to want someone, to be wanted back, to show up different and scared and try anyway. Two girls learning that love isn't about becoming the same person, it's about learning to tend something that needs both of you.
Yamada finds solace in her school's flower garden, a quiet refuge that matches her gentle nature. She is a timid, somewhat clumsy second-year high schooler on the greenery committee. Everything changes when Kase-san, the lively star of the track team from the next class over, catches her eye. The two couldn't be more different, and they have never exchanged a word, yet the morning glories Yamada plants slowly bring them closer. What starts as an unexpected attraction becomes a first romance, and each girl has to learn how to care for the fragile bond growing between them. The result is a short, soft slice-of-life romance about two very different girls and their first love.
