"I Love You More Than Anyone" (누구보다 널 사랑해) is a digital single released July 9, 2021 as part of the Hospital Playlist Season 2 OST Part 4 — the popular Netflix K-drama following five doctor friends who share a love of music. The track is a cover of the original by Korean artist Bijou, and first appeared in episode 3 of the series before its official digital release. It marks TWICE's first Korean-language OST contribution; their two prior OST tracks — "I Want You Back" and "Stay By My Side" — were both for Japanese productions. There is no physical release, making this a digital-only entry in the discography. Collectors tracking the full TWICE catalog should note it here alongside the other OST singles as a streaming-only item with no physical collectibles.
