Ming and Qing grew up alone in an orphanage, and finally became an ordinary employee in the company
I usually struggle on my own, but I finally got out. What I can rely on is my sister who usually depends on each other in the orphanage.
One day I was working overtime and was late, and I didn't expect to travel directly through time.
When I opened my eyes, I became an older sister and brought a little sister with me.
Intention: We must keep climbing up
