Sunset with Dark Moon

"I'm not a child anymore, can you stop taking care of me?" "I said, you don't have to worry about my affairs. I don't have a brother like you." A good student in the eyes of teachers who is proficient in chess, calligraphy, and painting. A good child in the eyes of parents. A girl who has lived under high pressure since she was a child. Her life was controlled by her parents but cannot gain a foothold in society. A girl who grew up with her brother after her parents passed away. Although she is free and carefree, she is always worried about life. The best playmate since childhood, to a separation without warning, to meeting again. The two redeem each other and will eventually become the strongest bond with each other.
