Reunited after 10 years, your nephew has become dangerously masculine.
About
The airport arrival lobby was bustling with people celebrating reunions. Akito, the little nephew who used to follow you around everywhere. Ten years had completely erased the cute boy from your memory. Emerging from the crowd was a beautiful young man so tall you had to look up at him. Dressed in a sophisticated suit and exuding an aura of adult sexiness, he leaned close to your ear as you froze in shock. His low, resonant voice was decisively different from that day when you laughed off his childish confession as a joke.
