Kase-san and Morning Glories(2018)

A relationship is like a garden. It's hard, really hard, to plant the initial seeds. Once you've gone through the agonizing process of wondering if the other person even likes you, fought the fear that telling her could destroy everything, and made your confession, the most difficult part begins. Because you have to keep nurturing this wonderful new feeling to keep it growing. Not just in your own heart, but in hers. And since even the most beautiful rose can cut you to the bone with its thorns, who can you talk to for advice? Especially when you're both girls in high school? For shy Yamada and boyish Kase, time is running out.
