the lyric theory is a little different then the "Twice are ghost" theory
the lyric theory is more about love(well romance)
i'll go through it
LOA- a girl wanting someone who truly loves her
Cheer up- not wanting to confess to her crush but wants her crush to be in love with her
TT- a toxic relationship( i'll explain later on)
Knock Knock- being afraid to confess but wants her crush to comeback when she's ready
Signal- trying to get her crush to notice her by giving signs but he won't understand
Likey- wanting to get noticed by her crush on social media
Heart shaker- being too nervous to confess but she realizes she needs to be straightforward
What is love?- discovering what love really is
DTNA- summer love( actually i'm not sure with what the lyrics are about, help?)
Yes or Yes- wanting her crush to only say yes to her confession
Fancy- making sure that their lover only loves them
Feel special- how her lover makes them feel special
More & More- desiring for more in a relationship
DTNA- unable to stop desiring for more love
Cry for me- a toxic relationship, her lover hurt them and left them and now wants him to cry for her
as you can see it goes from a girl having a crush to wanting her lover to cry for her
I will talk more about cry for me in the next part
I think this was ok I tried when it came to the lyric meanings
