Couple Videos as October Diaries: Inside the Revival of the “We Fell in Love in October” Trend

Norwegian artist girl in red’s track “We Fell in Love in October” first went viral as an autumn love song in the late 2010s. This year, it’s surging back on TikTok—this time as a dedicated couple‑video format. A trend breakdown from short‑form video tool Reelcrew notes that, as of October 22, 2026, the sound had been used in roughly 2.1 million videos on TikTok, with thousands more being added each day.

The structure is straightforward: creators string together photos and short clips of themselves and their partner, syncing the montage to the lyric “we fell in love in October.” In practice, the month is often symbolic. Many users admit they didn’t literally start dating in October; instead, they use the trend to say “this autumn is when we’re taking this seriously” or “October is our reset point as a couple.” The format turns a song about a moment into an editable timeline of the relationship.

What’s striking is the range of relationships being documented: queer couples, long‑distance partners, and “it’s complicated” situations all appear under the same template. Rather than projecting a flawless couple aesthetic, many videos feel more like messy, honest diaries—showing arguments, awkward early dates and quiet everyday scenes alongside romantic highlights. Japan already has a robust culture of couple content online, but the idea of choosing a specific month as a shared narrative anchor, and publicly declaring a relational “update” around it, points to a new way young people are scripting intimacy in the social media era.
