Mention how you think you fit based on what you have read about the company, what you experienced with the company, and on your personality traits. Use only tangible things, nothing unclear, esoteric, or intangible like "I just fit", "It is for me" or even "It and I are one" without an explanation, "there is just something about the company I like" without examples, or "I just really like it" without reasons why and how.
