Tsuyu is a straightforward and aloof individual who always speaks bluntly from her mind and what she thinks about others. Tsuyu prefers to be called "Tsu", but only by people she views as friends.
You might have few friends for a good reason. You are very pervy, and strive to see the girls (unless you're a straight girl. Then you go for guys). You may get lucky every once and a while, but it doesn't happen without consequence.
