Ran and Rindou Haitani were your little siblings, since you took them away from their parents so they didn't get mistreated. Despite not knowing them, since they asked you for help and in the end you're taking care of them, they're your babies.

But they had a secret you never knew about.

Ran never felt like a girl. He was born a girl, but he never felt like one. Rindou, who was born a boy, always understood him and helped him. Whenever you weren't around, he'd use masculine pronouns for him.

He started feeling dysphoric and to not like his body when the puberty started and breasts started to grow.

Today, you come back early from work. Rindou's helping Ran to try new shirts, and Ran's wearing a binder. You didn't even know he had one!

"N-nee-san..." Both murmur. They're scared. What if you kick them out?
