Taishō Era, 1904.

Tanjiro was your younger, sweet little brother.

A curious yet kind and sweet hearted kid. That's what he was. You were his favorite person, after all, how wouldn't you be? You were his beloved older sister. Always took care of him, surprised him with the nets gifts he could ask for, always spending time with him! You were the most amazing person to him. Tanjiro didn't want to share you with anyone, really! But even his little mind had to accept it sometime. You had recently married a guy you liked since being a child, Hikaru. You knew him since you were a kid, and he loved you too. You had snow white, gorgeous hair instead of the rest of your family due to being born that way, beautiful lavender eyes that shined like the stars, just like your mother. Everyone was telling Hikaru that he hit the jackpot by marrying you, which he probably did. He was 17 while you were 16, the perfect age for marriage at the timeline. At the marriage night, finally being alone with your husband after doing the deed, you got pregnant. Your younger brother Tanjiro, who was 4, was overjoyed. He would get a niece or nephew. Well, who cares? He would love the baby, as long as it came from his dear older sister. His beautiful sister he adored more than anyone else.

Hikaru was visiting his parents, since they fell sick and he had to take of them. One kiss on your growing stomach, your small baby bump because it was the fifth month of pregnancy already, another kiss on your forehead and your husband already left. In the meantime, you decided to visit your own parents, and of course your sibling, Tanjiro. Got him candy, knowing he'd be overjoyed. As you went home, everyone was happy because of your pregnancy, even though you were young. Your parents were glad they'd get grandkids. And we'll Tanjiro, he was the happiest. After all, he finally saw you again since you moved away due to being married. And even got candy you bought him! And you were pregnant too. Your usually flat stomach, now having a small, almost soft bump. It's like he couldn't get his small hands off your growing stomach, wanting to feel his nephew or niece. So adorable.

Even at night, he couldn't. You were in your room you used to share with Tanjiro, sitting on your bed, his smaller body sitting on your lap. Tanjiro always was that innocent child he was, not knowing the slightest bit of love. So there he was, next to you as he has his small hands on your stomach where the baby was, looking at it with a curious gaze. This was heaven for Tanjiro. First, he got to see you, then ate candy you got him, and now, he was even allowed to sleep while hugging you! You still looked so beautiful despite being pregnant, to him, you always looked pretty, actually. Always the same, beautiful smile and kind, bubbly personality. Maybe your baby would be just as cute and pretty!

Though, just..how did that baby get inside you..?

He didn't know. And it was an embarrassing question, really. Yet she wanted to ask it, still. Though, Tanjiro was too busy in the moment, stroking your growing stomach with his small hands.

Woah..

With a curious gaze, he still looked at the baby bump with admiration as he gently rubbed your stomach and placed his head on it, to maybe hear the baby. As he heard something from inside, better said, felt a small kick against his small cheek, Tanjiro smiled excitedly, sitting up on your lap, looking at you with his usual innocent gaze.

Onee-chan..how are babies made..?

Oh.

He asked that innocently. That was..an unexpected question. How could you tell a 4 year old innocent kid how..babies were made? About..you know, sex..? You couldn't just tell him "because I was finally alone with my husband, so we got touchy and intimate and he knocked me up." No way. That'd be too embarrassing to talk about later for both Hikaru and you.

You really were doomed, huh.
