i didn't know it was about bam !! that's so sweet. them being a thing? eh maybe. i think it's more likely that as we know they were just best friends and thick as thieves.

just read the lyrics and honestly it gives me more the feeling of someone who lost a person they could always turn to. chan lived in the day6/got7 dorm so there was probably a possibility that he was meant to debut with got7 or at least thought he would.

and then got7 debuts in 2014 and day6 debuts in 2015 so essentially chan is left alone bcs they're moved out of the trainee dorms into a dorm for the group. it honestly reads as very very lonely and feeling left behind to me. reminds me of when my best friend moved to the other side of the country when i was a kid and we spent basically all our time together and suddenly i had to figure out what to do bcs my routine hadn't changed really (i didn't pick her up on the way to school) but the person i did those things with were gone.
