How is love?

Two anime characters hold hands in a close-up, then the scene shifts to them standing together in a park at night under a canopy of blooming cherry blossoms, with petals falling around them. The view changes to a close-up of their hands clasped, then shows them facing each other in a field of pink flowers, before cutting to a dark, tense scene of feet on a path, and finally to a close-up of a character's face overlaid with an x-ray image of a skull.
