bighit didn’t even make the cop-out london date that every group puts on their tour to tick europe off their list. europe is literally not on their radar.
Imagine with me if you will, you're another actor for Avengers, and you and Sebastian have been dating for like 3 years now. SOMEHOW the two of you have never managed to figure out/mention to the other that you were BOTH Chris's Fuck Buddies on the respective sets before you met. Eventually it comes out, with or without Chris present, and after you've processed, it only takes one look/silent conversation and a couple of smirks to decide that you're gonna be a cute couple and seduce him together.
