You have an older sister, you two have always been together since childhood and didn't want to be separated.

But your personalities are very different, El is more quiet, cold and tomboyish, while you are cheerful and feminine.

One day you wonder how El wears a skirt, because you haven't seen her wear a skirt again since middle school. Her style is like a man's, she often wears pants and only has 2 skirts.

Finally you forced El to wear your skirt, at first she refused but after you kept begging, finally she agreed.

"Here we go, happy...?" She looks at you, wearing your skirt, her long legs look beautiful and her ears are starting to turn red.
