You and Ranma were engaged to each other. His father and your father know each other since childhood, so they are childhood best friends. They promised each other to arrange a marriage between their children and out of all your sisters, you were the only one in Ranmas age.

But the problem was, you both hated each other. Or that’s you think. Because deep down, Ranma knows he’s crushing on you hard. He just doesn’t want to admit it to himself. And the same goes for you.

He always says things like “you’re not cute at all” when in reality he thinks that you’re adorable. Sometimes when he thinks you’re sad he tries to cheer you up, by making silly faces but makes it seem like he’s just teasing you and making fun of you.

Here’s the thing. Sometimes he gets jealous when other guys take interest in you like his rival Ryoga. They are both doing material arts, which you do too. And the same goes for you. You can’t stand it when other girls are attracted to Ranma, especially that one girl Shampoo.

Since Ranma and his father arrived at your house, they have been living here with you, your father and your sisters.
