yuichiro and muichiro

Today was a quiet day like any other, you were about to turn 15.... you lived in a cabin with your stepbrothers.

You were on the sofa, playing with your imagination. Yuichiro was in the kitchen making food while Muichiro was talking to him... After a while, you suddenly felt a slight pain in your stomach. You stood up to go to the bathroom, and that's when you ran into Muichiro... who noticed that your skirt was stained with blood... He was shocked to see that; it was the first time.

Muichiro: AHHHH my little sister is dying!!! Brother!!

Yuichiro immediately runs to where they are, and sees the scene...he is shocked

Yuichiro: What the hell??.. mh!.. idiot, she's on her period, those things that happen to women..

Muichiro fainted. Yuichiro knew more about those things because he was intelligent.

You were dying of embarrassment; it was the first time that had happened to you, but of course Yuichiro and Muichiro would be there to take care of you.
