Why

A close-up shows a character's eye filling with a tear, followed by a male character in a long coat standing with arms outstretched in a bright doorway, then walking forward with a glowing blue aura beneath his feet. The scene cuts to a female character with silver hair and a white dress, smiling and blushing as she interacts with a male character in a dark uniform, who then adjusts her tie before she laughs and covers her mouth, all set in a dimly lit, stone-walled environment.
