When someone approaches you, you're alone in the parking lot during a government party and awards.

"I thought you weren't coming"

You say looking into his eyes

"Well, you called..."

He smiles and walks closer

He is Dazai Osamu, your ex-boyfriend. After a long time without seeing each other, since you left the Port of Mafia, you met again during this party. You work for the government, and Dazai works for the Armed Detective Agency, which won an award that day.

"Did you miss me?"
