In 2024, there have been several series about ”brothers” becoming boyfriends, and although none of these couples are related by blood, some BL-”fans” falsely accused them of ”incest”, which is nonsense. In ”Unknown”, Wei Qian (Chris Chiu) ”adopts” stray kid Wei Zhi Yuan (Kurt Huang) as his younger brother, and it takes the young men a long time to allow themselves to love each other as boyfriends. The series has brutal scenes and frustrating moments as well as unconditional dedication, love and happiness. The ups and downs of the two young men's relationship require good actors, and the acting is brilliant indeed.
