I Love You So was released by American indie pop band The Walters in 2014 and found a second life years later on TikTok. Short excerpts of its chorus spread as users attached it to relationship edits, anime montages and sentimental tributes, turning an older album track into a familiar trend sound. Its simple, repeated declaration made it easy to recognise even out of context, and the melody became shorthand online for devotion, longing and bittersweet romance across fan communities.
