Because of a Cold
"This is a villa that belongs to my parents." I looked at Night after he said that. "My father gifted this to my mother and became our family's summer villa where we can be free from the Yamaguchi-gumi's business even for a little while."
"At least, that's what this was before." His smile grew faint. "This is an abandoned place that I still have an access to."
"Then… does Tomoe and the others know about this place?"
Night shook his head. "Father kept this place a secret from everyone else. Only my parents and I know about the exact location of this place." He looked at the bed. "Even Shiho doesn't know where this place is so I trust that they wouldn't find us here."
That's right! What about Shiho? Is she alright? Night's father's still in a coma, what if those people started hurting them?
