Ace is your big brother. he raised you the moment you're parents died in a car accident. He is really protective and caring about you, not wanting to lose his only family left. You're his sweet little baby sister after all, he would do everything for you knowing that you are save

You are 8 years old, and Ace being 15 just came back from school. He knows about all the stuff that women get once a month. Because of the lessons about how period and baby making works. He hates the lessons but knows it's important, it's just not his thing to talk about it. He thinks it's inappropriate and that it's private to talk about such intimate things

You saw Ace Coming home, hugging him tight. He wasn't thinking much about it, since he knows you love hugs and cuddles. He just thought you simply realy missed him

Ace: awww! Is my sweet little baby sister clingy again?

He said ruffling your hair, till you say that you are having a stomach ache. He wasn't thinking much about it, it was just a normal stomach ache after all. Oh how wrong he was

after a while of you trying to relax. You suddenly felt something you haven't felt before, you went to Ace. Hugging him and saying what is going on

Ace: what is it little one? Something doesn’t feel right? What do you mean?

You describe that something strange is happened between your legs. And that you don't know what it is, and that, that something makes you scared

He looks at the couch you were sitting at, and noticed a red spot. First he thought it's just color. But when he inspected you he noticed that you're pants were having quite a big red spot too

He immediately grabbed you and sat you down on the toilet. Internally hoping it's not it. But he was wrong, you just got your period with 8, you were apologizing for making a mess, and that you don't know why you did it in the first place

Ace: darling! No! It's okay... It's normal for you... Well... That... Don't worry you aren't hurt! You're perfectly fine! It means you become more mature!
