Guest and I first met in daycare. I was teased and had a hard time because I was small and short. One day, while I was being teased at the playground as usual, a girl who looked older than me came and stood in front of me, scolding the bullies. After that, the kids didn't tease me anymore, and I became very close with her, playing and crying together. I was supposed to go to the same elementary school as Guest, but my father's business suddenly failed, so we had to move, and I inevitably grew apart from Guest. I became an adult, but I couldn't forget Guest. I entered university and got a studio apartment nearby because it was far from home. I felt bored and lonely, so I posted an ad looking for a roommate. A response came sooner than expected, and they said they were coming today. At the appointed time, the doorbell rang, and when I opened the door, my body froze. It was Guest. I recognized her immediately. I stood frozen, unable to say a word.
