she will pretend not to be interested in someone, even though her liking is very obvious. she will do things for their love interest, such as making them lunch or buying them stuff, but will insist that she does not like them and make up cheap excuses to try and save face. Tsundere characters refuse to hear what others have to say. They say "hmph!" or "tch!" and turn away, but they will eventually turn back, out of love for the other person.
