Forever 🙈

Two anime characters with wide eyes look up in a dimly lit hallway, then the scene cuts to a girl with light green hair and a flower in her hair against a starry background, followed by a boy in a white shirt reaching out with a pink, flower-filled background, then a girl with blonde hair closing her eyes in the same setting, and finally the same girl smiling while carrying a red guitar case in a park with blooming trees.
