Bachpan Ka Pyaar rose to fame in 2021 when a video of Sahdev Dirdo, a young schoolboy from Chhattisgarh, India, singing the song in class spread across Instagram and YouTube. His earnest performance was remixed, recreated by celebrities, and turned into a popular audio for reels and short videos. A commercial version with rapper Badshah followed the same year, pushing the phrase further into mainstream culture. The original clip remains the version most editors reuse for school, nostalgia and first-love jokes.
