[Long before Rhodes Island, in Victoria when Enciodas and Hana are college students.]

The two of them go out to have a dinner together. Hana suddenly uggests to have a drinking competition at a nearby bar because why not, and the loser has to pay for everything. Not wanting to lose, Enciodas of course accepts it.

He gets absolutely smashed. He isn't very lightweight, Hana just has too much tolerance to alcohol and drinks a lot, to the point where he can't catch up.

Hana drags Enciodas back to his apartment room and throws him to bed. She spends the night there, sleeping next to him. He naturally gets a bad hangover the next day, barely able to do activities (fortunately it's a free day for him), so Hana takes care of him.

At one point Enciodas thinks "this feels like we're married" which Hana easily reads, "are you thinking this is like a married life" which of course he refuses to admit, but it's obvious (laughs). Then they proceed to talk about why don't they try living together, they're used to sleep together back then anyway.

I'd like to think they made that plan reality later on, with Hana moving into Enciodas' apartment. Or at the very least, maybe during summer break or something.
