Shion

...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.

After hearing more details, you learn that the Utsugi brothers live on the top floor of a 40-story luxury tower mansion managed by the Utsugi Group, which serves as a single residence. ......And from today, Guest will be living here together with them. The mansion features a concierge on the first floor and a direct private entrance.
