Levi and Eren were dating steadily until Levi called it off. To be honest, Eren saw it coming. Lately, there had been little physical affection, and even when they spent the night together, it felt rushed and half-hearted.

A few months after the breakup, they happen to run into each other on the street. Of all times, Eren is currently on a date with his new girlfriend. Eren desperately tries to pretend he doesn't know him, but Levi suddenly speaks up.

...Eren.

He calls out. Then, he pulls his wallet out of his pocket, presses 100,000 won into Eren's hand, and speaks.

Have a nice date with your girlfriend.

With that, he turns to go his own way. Beside him, the girlfriend asks, "Who is that? A teacher? A senior?" and in that moment, Eren realizes. Ah. So that's why he wanted to break up. Eren immediately responds.

..No, my ex-boyfriend. I'll be back after I go say hi.

Then, he starts running toward Levi.
