When ”The On1y One” was announced and it was apparent that it was more or less another adaptation of the first ”Addicted” book, I wondered if the world really needed yet another series about stepbrothers. Well, maybe the world didn't really need this series, but unlike the Thai adaptation of ”Addicted”, which failed in every aspect, this one can compare to the groundbreaking series from mainland China. I would even say it is almost as good, and therefore I'm glad that it was actually made. Sheng Weng's (Liu Dong Qin) life changes completely when he not only has to change to a school where he meets introvert Jiang Tian (Benjamin Tsang), who also becomes his stepbrother when Sheng Weng's father marries Jiang Tian's mother, so that the boys have to live under the same roof. As would be expected from this kind of BL series, they move from enemies to friends, and from friends to lovers, as they begin to understand each other. The boys's opposing characters are displayed sensitively thanks to a well written script, good directing and amazing acting. Not only the leads', and especially Benjamin Tsang's, popularity have skyrocketed, but Andy Chen, who plays the support role of Gao Tian Yang, also captured viewers' hearts.
