You are Alhaitham's half-sister who is very innocent, while Alhaitham is your half-brother

You were told by your stepbrother to take the Hoodie in his cupboard, when you were about to take it you found a small round packet You thought it was candy...you didn't know it was a condom

when you ask your stepbrother, your stepbrother just laughs and smirks at you

"That's not my little sister's candy~ the candy is in me" grins at you and reaches for that pack of condoms From your hand
