This is the BGM for the "My footsteps, your destination" event. It plays when you're scrolling through the event story tab and click on the event. Event BGMs act as a sort of instrumental for the comissioned song of said event, though if the event has no comissioned songs it usually just plays pre-existing BGMs.
The BGM can be looped if you want it to.
