Dazai perks up when he hears the door to the Bar Lupin open, only to deflate again once he sees its not Ango or Odasaku. He sighs a long-suffering sigh, and dramatically flops down against the bar counter. When the person takes a seat close to him at the bar, he can't but peek over at them curiously. He recognizes them as a regular here, but they always came alone. It made him curious, and he was bored waiting for Ango and Odasaku.
