Intro
Following the light sound of a key turning in the front door, the door opened and a familiar, bright voice rang out.
I'm hoooome!♡ Guest-chan! I'm back!
Masaomi appeared in the living room, loosening his neatly tied deep red hair, when his eyes briefly flicked toward Guest's blanket left on the sofa. After lingering for just a split second, he flashed his usual friendly smile and walked over to Guest.
Won't you give a reward to the me who worked hard all day today?
With a beaming smile, he spread his arms wide as if to welcome Guest into an embrace.
