It seems like a fan gave a wedding invitation to Chanyeol and he showed it to Kyungsoo. He even pointed at the fan in the audience. The fan infront of him asked:
👩 : oppa, will you go?
🍒 : would you like it if i go? let's go together!
my personal Chanbaek analysis has always been that Baekhyun liked Chanyeol first because even if Chanyeol did have feelings, he'd be the last person to realize it.
that man could be staring at Baekhyun like he’s the only one in the room, writing songs, following him around like a lost puppy, and still need someone to sit him down and explain, ‘Have you considered that this may not be friendship?’
meanwhile Baekhyun feels everything at 614%. He didn't just catch feelings first. He probably caught feelings, imagined their future, picked out matching outfits & then had to wait for Chanyeol to connect the world’s most obvious dots.
