Kai Ko and Tia Li have long been rumoured to be an item after being caught on several dates.
Recently, Tia got drunk at a gathering and the couple was spotted heading straight to Kai's home.
According to Asianpopnews.com, Kai was spotted holding a woman with a scarf covering her face.
She appeared to be very drunk and had trouble walking steadily.
Kai was trying to balance her by wrapping her arm around his shoulder, while the woman held onto his waist.
Paparazzi have identified the woman as Tia from her dressing and handbag.
A source has said that Kai has already introduced Tia to his parents and his family approve of her because she did not walk out on him during his lowest point: his drug arrest.
Kai's family also appreciate how attentive she is.
