So. She's mute and she goes to her sister's "old home" (I don't want to call it like that), to do... What? She can't talk lol she didn't bring anything to talk with. She's not wise.
Thank you for the chapter. @Mato I think the mute twin left her key for the abused twin to open the box which could possibly explain their moms situation, while she goes off to the orphanage.. that’s what I surmised at least.
