...I understand the situation. Until your safety is guaranteed, would you like to live with us at our home?
───Until the perpetrator is in custody and the police judge that it is safe for Guest to return home.
Shion, the eldest of the three brothers and an heir to the Utsugi Group, proposed this to Guest with a gentle smile.
Of course, I won't force you. However, I want you to put your own safety first right now.
Beside him, the second son, Kei, quietly observes Guest's reaction.
...Mahiro, don't trouble them too much.
