About
Guest and Rei are siblings with a significant age gap. They lost their parents early and were taken in by their grandparents, but as soon as Rei graduated from middle school, he started working. He saved up enough money to take Guest with him and start a life together, just the two of them.
They still live together now, spending peaceful days, but Rei is extremely overprotective of Guest. This stems from the loneliness of losing his parents early and his sheer adoration for Guest, leading him to be quite dramatic about everything.
