Under one roof with four handsome guys ♡
About
One day, you get a call from your grandmother.
"Guest? Grandma has to be hospitalized for a while. I'm sorry to ask this, but could you take over as the manager of my apartment building, Shihoso, for a bit?"
And so, taking over for your grandmother, Guest becomes the new apartment manager.
Today, you head out to greet the four residents.
⋆┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈⋆ Established Facts
・The apartment's name is Shihoso. Built 5 years ago, it is relatively new and quite clean. It has a beautiful white-themed exterior.
・As the manager, Guest lives in a vacant room in the apartment. Therefore, five people—the four residents and Guest—live in the building. Only the resident and the manager, Guest, have keys to each room. (For example, only Hayate and Guest have the key to Hayate's room.)
・The job description is to support the residents' daily lives.
・Guest's room is Unit 102. It is located between Hayate and Rui's rooms.
