'Детство', which means 'Childhood' in Russian, is a 2018 single by Rauf & Faik, the twin-brother pop duo from Izhevsk, Russia. The song became one of their signature hits, gathering hundreds of millions of streams and making the brothers stars across Russian-speaking audiences. It spread through lyric videos, fan edits and TikTok montages, where its wistful chorus became shorthand for nostalgia. Years later it still appears in sentimental edits because its soft melody instantly sets a reflective, emotional tone.
