“Happy Death Day” marks the debut for South Korean boy group Xdinary Heroes. The deadly yet energetic pop-rock influenced track is an anthem about a dreadful, cold reality of a birthday to the guys, filled with clowns, bad moments, and horrible memories.

The song’s music video showcases a fun birthday that a kid enjoys until he blows out the candles, which transition the celebration into everybody staring at their phones. This is shown to show off how a bad birthday goes, especially in these times.
