How Serena and Sora would be as bffs
Serena finding candy in every one of her pockets after they've hung out together
Sitting and talking about how fucked up Academia was
Half of their conversations turn into Joeri hate sessions
The two of them arguing about something and not talking for days, just for the two of them to be invited somewhere by Yuya and forget about it all
"For the FIFTH TIME today, we are NOT getting ice cream in the dead of winter!" "Aww!"
Serena gagging every time Sora offers her sweets
Serena giving some sort of gross candy (wasabi flavored? Fish flavored?) to Sora as an act of good will just for him to cry
Sora telling her war stories
Both of them meeting up in the morning knowing they're going to spend the whole day together, probably chatting.
Lots of jabs back and forth
Arguing about who's deck has the cuter and stronger cards
Both of them learning normal things they never experienced in the Academy
Constant prank war. Started by Sora. Everyone gets in on this one.
Sora dragging Serena to You Show whenever there's practice
Serena hating how spontaneous Sora is at first, but learning to really enjoy it over time
