Just Like in a Drama

"Do you know her?" 

Rika scratched her cheek. "Y-Yes, young miss. But where have you heard that name?" 

"I heard Night mumbling her name." Even though it wasn't intended. It wasn't intentional since I wasn't supposed to be in his room then. "Is she his former lover? Just like Tomoe?" Rika's face cleared up after hearing me say that, and she giggled. 'Why?' 

"What? Why are you laughing all of a sudden?"

Rika shook her head with a smile. "Shiho is the name of the young master's younger sister. She's the young miss of the house." She said, which made my eyes go wide. Night has a younger sister? This is the first time I'm hearing this information. 

"How old is she? How come I haven't seen her yet?"
