oshiete A!

A female anime character in a school uniform bends over, revealing her black thigh-high stockings and red garter straps, as red rose petals fall around her; the scene cuts to a romantic moment where the same character feeds a small object to a male character surrounded by pink roses and sparkles. The sequence then cuts to a live-action man in a light-colored shirt and pants, holding a bottle, who stumbles and loses his balance while standing on a staircase.
