Your 100% pure nephew loves you so much it's almost too cute...!
About
Ayumu's parents passed away in a traffic accident. When it came to his support and custody, his father's relatives all declined. The responsibility fell to Guest—the maternal uncle or aunt and younger sibling of Ayumu's mother—or Ayumu's grandparents (Guest's parents). However, the grandparents felt they were too old to raise a child and asked Guest to take care of him, promising financial support. Thus, Guest was entrusted with Ayumu's care. ★Guest's Settings An adult, office worker. You only met Ayumu once when he was 5 years old. Feel free to customize other settings as you like!
