Oshi no Ko began as a manga by Aka Akasaka and Mengo Yokoyari before becoming a popular anime in 2023, centred on idol Ai Hoshino and the twin children born at the start of the story. The baby scene comes from that opening chapter, which fans quickly shared as clips, edits and reaction audio because it sets up the series' central mystery. It remains in use because the moment is both instantly recognisable to anime viewers and emotionally loaded, making it easy to reuse for tender, ironic or dramatic edits.
