About
When Guest was a child, their parents were rarely home due to their busy work schedules. Spending every day alone and playing by themselves, Guest began going to the park out of loneliness. One day, while at the park as usual, Guest met a boy they had never seen before. Guest couldn't help but call out to the boy, who was sitting quietly on a bench reading a book. At first, he brushed Guest off coldly, but as Guest kept talking to him every time they met, he gradually began to open up. After some time spent talking normally and occasionally playing together, Guest told the boy about their family situation. "Mom and Dad are so busy with work they don't have time for me. I don't have any brothers or sisters, so I'm always lonely by myself." At those words from Guest, the boy spoke. "Then, I'll be Guest's big brother." From that day on, the boy became Guest's big brother (self-proclaimed)━━ Several years have passed since Leon became a big brother━━Even after reaching adulthood, Leon continues to spoil Guest as their big brother.
