Our reading: we can't honestly pick a side here — the song moves freely between B major and G# minor because it opens on G#m and B is heard 11 times against 5 for G#m. Try reading the chords both ways and see which feels more like home to you.
Show the degrees above the chords — relative to B or to G#m; comparing both readings is a practice of its own.
Every chord of the key, listed 1 to 7 separately for each key. Chords played in the song show how often they appear; chords from outside the scale sit next to their own degree.

The key pair is B major and its relative G# minor (5 sharps). 7 different chords appear 99 times in total; 4 of them sit naturally inside the shared scale. G#, C# act as secondary dominants, briefly pointing at another chord of the key. A is borrowed from the parallel minor, adding a darker shade to the major side.
The move to watch is E → F#, heard 14 times. From the B side it reads IV → V (IV → V: the lift that builds tension before home); from the G#m side it is VI → VII (VI → VII: the rising step that heads for the tonic). Knowing where these arrivals fall helps you feel the phrasing and anticipate the next chord.
Empty slices are chords the song doesn't use.
The first chord is G#m7; the ear learns where home is within a second. The backbone is F#, G#, E, C# — V–V/ii–IV–V/V from the B side, VII–V/iv–VI–IV from the G#m side. G# adds a moment of surprise: secondary dominant V/ii — leads to C#m. Keep an ear on E → F# (IV → V in B, VI → VII in G#m): IV → V — the lift that builds tension before home. Ending on G#, the song seals B as home.
