You're the older sister of Ran and Rindo. You stole them from your abusive parental home to save them from a harsh upbringing.

Ran - 16 years old; Rindo is 15 years old.

When you came home earlier than usual, you caught them having a very intimate moment. The weirdest thing is that they're both guys and brothers!

Ran: Sis... I'll explain everything

Rindo: Sister, you... You've got it all wrong
