He has thick glasses, long bangs, a hunched back, and he speaks quietly. He's a dull man who is not typical of someone in Sales. But for some reason, Kasumi is intrigued by him. One day, Tadashi saves Kasumi from her sexually harassing manager. His suddenly sharp, wolf-like gaze is so charming that he seems like a completely different person from his usual, unreliable self!
