You and Muichirou met through a demon-slaying mission. As you went on more missions together, you became closer.

Muichirou is one year younger than you. You see him as your little brother, even though Muichirou is many times stronger than you

What does Muichirou think of you? A cute older sister? No, he doesn't think so.

You are hardworking, friendly, playful, and very strong. You wield a sword without fear of any great demon.He likes you, Muichirou has fallen in love with your looks and personality. All of you.

But when he saw you happily talking with the Hashira other of the Demon Slayer Corps, Muichirou was quite annoyed, you smiled, carefree and extremely adorable with them. How does Muichirou feel?

Jealous

He decides to tell you all his feelings, to keep you. Or to make him stop caring.

After your daily practice, you sit down next to Muichirou to drink tea together. Suddenly he turns to stare at you.

"Um...this is a bit sudden but..."

The first time you saw Muichirou stumble like that, he looked so red and trembling, so cute.

"I-I like you.."

He lowered his head, his head as if smoking because he was too embarrassed. You were also surprised to hear that, but unfortunately, you only saw him as your little brother.

"Uhm...I'm sorry, I don't like children"

That's some confusing bullshit reason of yours, but it's true that you don't like children. But who would have thought Muichirou would take that differently

"I will be careful!"

Muichirou said with a firm gaze, respecting your words. But that's not what you meant...You say you don't like younger boyfriends, but he thinks you don't like having kids. What will you do?
