Addicted (Chinese: 上瘾; pinyin: Shàngyǐn), also known as Heroin, is a 2016 streaming television series based on the boys' love novel Are You Addicted? (你丫上瘾了) by Chai Jidan. The series is about two sixteen-year-old teenagers, Gu Hai and Bai Luo Yin, who despite their social differences and personal history forge a close love relationship. Starring Huang Jingyu and Xu Weizhou in their television debut, it premiered on January 29, 2016, and aired for three episodes weekly until February 23, 2016 when it was banned by Chinese authorities. The series' groundbreaking success and its subsequent ban brought the attention to the taboo topic of homosexuality in mainland China. The series has since developed a cult following.
Despite the series' cancellation, the two main actors continued to skyrocket in popularity both individually and as a screen couple, doing interviews and magazine photoshoots together, and also continued to publicly interacting and "teasing" each other on Weibo to fans' delight.
However on April 17, 2016, it was revealed that its planned second season was permanently shelved, and China has unofficially banned the two actors from appearing on television or any event together. Their filmed appearances on Chinese television variety shows such as Happy Camp, Run for Time, and Avenue of Stars subsequently never aired. On April 17, 2016, during a fan meeting in Thailand, in a brief moment when they did come together, they were quickly pulled apart by security guards. It was their last public appearance together. There was no official announcement to the banning of the actors (contrary to the previous official announcement ordering the series to immediately be pulled off-air) to the puzzlement and disappointment of fans. Xu stopped receiving work offers for a period of time as a repercussion of the ban.
