Twins signed to Emperor Entertainment Group and were formed on 18 May 2001. According to Mani Fok, EEG's plan for Twins was to emulate the success of the Japanese duo KinKi Kids. In August 2001, they released their debut extended play "Twins" (AVEP) with hit single "Open Love, Secret Love, Tutoring Institute". This EP contained 3 music videos and 6 songs. As part of album promotions, Twins collaborated with MSN to make personal pages and web games. In addition, EEG bundled gifts and coupons with the EP, so that teenage album owners got more value from their purchase by receiving things like hair care products and vouchers for dance courses. It went platinum in its first week of selling. In November, Twins released their second EP "Twins' Love", which contained 8 songs and 1 music video for the lead single, "Slam Drunking Love".
