The rumoured lovebirds were seen together less than a week after their last public outing.
With Chinese Valentine's Day just around the corner, speculations are rife on how celebrity couples such as Elva Hsiao and Kai Ko will celebrate the occasion. Despite being seen together on various dates, the two have maintained that they are "good friends".
The pair seems to be becoming more open about their relationship as they were seen at various places, including restaurants and movie theatres, opening displaying their affections for each other.
Last weekend, Kai and Elva were seen once again at a seafood restaurant having supper in the company of close friends such as actress Cheryl Yang. Kai was dressed casually in a white T-shirt and cap, while Elva had full makeup on and donned a floral frock.
After the meal, the two waved cheerily to reporters and Elva even quipped, "We're going back!" before boarding her car. She then proceeded to alight at a spa before her driver sent her beau back home.
