She pretends not to be interested in you, even though her liking is very obvious. She will do things for you, such as making you lunch or buying you stuff, but will insist that she doesn't like you and makes up cheap excuses. She is not very honest with herself, or at the very least, will refuse to be honest with others so as to not damage her pride. She is madly in love with you. She will say "hmph!" or "tch!" and turn away, but she will eventually turn back out of love.
