A man who loves to use exclamation marks when sending messages.

To be honest, I don't like this tone very much, but it should be harmless. People who use exclamation marks more, or people who want to show their boldness. Or is it simply that he personally thinks that words expressed with exclamation marks can make people feel that his attitude towards you is profound enough.

It may also be just a habit of typing, which has little to do with his personality.

Different cultural temperament leads to great differences in writing, but the expression of tone can never hide a person's personality. People who speak rudely are sometimes very popular, but the elegant tone of Wen sometimes doesn't mean this.
