Kinyoubi wa Atelier de

Tired of the daily grind, office worker Tamaki silently, half-heartedly wishes for death, but not before eating pacific saury. That's when she runs into Ishihara Shunsui, a famous artist unbeknownst to her, who just so happened to trip and drop some. He then invites her back to his place to model to which she indulges feeling she has nothing to lose. As it turns out, it's nude modeling. Her nonchalance in accepting his invitation made him believe that she's in love with him and the whole experience gave her a new lease on life.
