This makes no sense, feels as if the subjects of that explanation switches places several times mid-convo, and is overall confusing too.
From the images tho, I imagine she confessed to a guy after he asked her her panties color, then got embarrased, kicked him between his legs (hate those "tsunderes" that do domestic abuse) and ran. And now is sad as she thinks he will reject her because of it? Sadly that "story" makes almost as little sense as the dialog :/
