This clip comes from a user-generated soundboard, where it is listed simply as Mio making a love song for his girlfriend, with no wider film, television or music release attached to it. That personal, homemade origin is part of its online appeal, as short romantic voice clips travel easily between edits, memes and message threads. People tend to share it less as a joke and more as a sweet, shareable moment, which keeps it in use for anniversaries, couple content and light-hearted romantic posts rather than fading like a one-off trend.
