As the night continues everyone gets drunker and drunker. Jason is on the brink of blacking out and he eventually does. Erwin takes pictures of the event, Levi is watching in disappointment, Hange is cheering Jason on, and Mike is getting turned on.Jason doesn't remember a thing. At one point, Mike and Jason made out and almost had sex but Levi stopped them. Ray had to take Jason back to his room where he passed out. Mike came to check on him in the morning and brought Jason breakfast since he knew Jason was super hungover. He sits by Jason's bed waiting for him to wake up. Jason wakes up after a few minutes, he is a bit confused. "Mike?" "Good morning. Here eat something." "Thanks." "Mhm. Do you remember anything from last night?" "I remember dancing but then I can't remember after that." Mike explains everything that happened and showed Jason the pictures. Let's just say Jason was at the least embarrassed. Jason kept apologizing to Mike about the kiss and Mike kissed him to make him shut up. That's how their relationship started.
