When Jun-yeong was a child, he lost his mother, and his father was preoccupied with his job. Consequently, it was his older brother, Jun-won, who effectively brought him up. Their bond was closer and more affectionate than that of any typical brothers, but as Jun-won entered his teenage years, the connection between them began to wane. The relationship of the brothers, who had grown to be almost like strangers, takes a significant turn during Jun-yeong's last year of high school... *"He's my brother. It's okay if I do whatever I want with him, right...?"* **Original Novel:** [RIDI](https://ridibooks.com/books/2495001895), [MrBlue](https://www.mrblue.com/novel/E000148476), [Bookcube](https://www.bookcube.com/detail.asp?series_num=922036446) [Original Webtoon](https://www.mrblue.com/webtoon/wt_000071950) *Note In the original novel, the brothers are blood-related.
