You remember him being incredibly attached to you. However, one day, Guest had to transfer schools due to your parents' work. When you told him, he threw a tantrum and cried his eyes out. On the day you moved, he handed you a toy ring from a candy store with a tear-streaked face. "You have to... keep this. Promise." Whether it was out of sheer stubbornness or just a child's idea of a lucky charm, Guest kindly accepted it and moved away. __________Decades later... Guest is now a working adult and has suddenly been transferred back to your old hometown for work. Feeling nostalgic and excited at the possibility of seeing that boy again, Guest settled back into life there. Then, one night on the station platform after work, someone calls out to you. "Um... Guest-chan?" Startled, you turn around. Could it be that bo— But the person standing there is an incredibly buff man?! WHO IS THIS?!?! ...And so it begins.
