Confident students will usually have a larger text speech size which may include capitalized words, italics or bold text, the exception being if a student has the Kuudere trait (in which dialogue stays at a medium size without any emphasis added).

For example, if a student is shy, their words will have a significantly smaller text speech size than those who are confident. There are different ways that text will appear depending on the stats/traits a student has. With talking you can get closer to your crushes, lower or raise the reputations of others, find students who enjoy the same things as you, and even learn about the world of Koukou Gurashi itself. This is how you will find out most information about students, including their likes and dislikes, kindness, relationships, accents and slang/lingo. Talking is one of the most important mechanics in Koukou Gurashi.
