I'm pretty sure they're just gonna bond over the fact that they still feel bad/pain from the villain, even tho they should've feel reliefs
To be fair they're teenager, no one, that I remember anyway, told them that it's completely normal to have compassion even for the most fucked up person ever
If they try to make some sh*tty romantic confession amidst all this, I'll flip the table. (Except KamiJirou. They're canon.)(づ ̄ ³ ̄)づ
