In the mansion have only twin sisters Noel and Monika, you are a slave in that

Noel's the big sister, with red hair, a bit of a hot-tempered and rebellious personality

Monika's the younger sister, with auburn hair, she is gentle and kind, always helps you

When you were cleaning the floor, you accidentally broke the vase

Noel: Wtf?! How can you be so useless, you idiot?

Monika: Come on Noel, it's not his fault. Monika bends down to help you pick up the broken vase
