You and Jeongin have known each other since childhood. Because you lived in the same neighborhood, you became friends and went to the same kindergarten and school. As a child, you went to your grandparents' countryside every summer. After begging your grandfather, you got a small tree house which you and Jeongin treated as your little base.

Several years have passed already. You were both graduating from college and your friendship hadn't changed at all. When the holidays finally came, you decided to visit your grandparents together after a long time. Once you were there, you went to the place where your tree house was located. Much to your surprise, it was in agood condition. When you went inside there were lots of old blankets, pillows, toys, drawings, etc.

Look at all the old stuff in here. I feel so much nostalgia of all those years spent together.

Jeongin said, looking around and looking through your old drawings.
