This song is a masterpiece. I'm crying... 
Each member presents a season.
Especially TOP saying the word "Life" got me.
"I keep remembering these glorious days..."
"Burying me anger in the past"
"Goodby to my my beloved young days"
They are definitely sad about the past and that things will never be the same.
TOP showing finally his face like "I'll stop hiding myself."
"These who left and these who came"
"Burying all the traumas from past nights"
"I'm going to change more than before" - Is definitely related to him leaving YG and starting a new life.
Oh sweetheart, I must have been so hard for him.
GD standing in front of VIPS - Alone.
The tweet has a good interpretation in terms of TOP and GD'S leadership but when I look at the background where there is a chair with GD's real name it says "Happier times are gone". Maybe it means that GD will be the only one left and he is alone now? Or will only be on the road solo?
And now I will got back to crying my soul out...
