Up until that time, Seventeen, the South Korean boy band, has not made any official announcements about their dating lives. K-pop agencies typically keep their artists' personal lives private to protect their privacy and to maintain the image they project to the public.
It's essential to respect the privacy of celebrities and allow them to have personal lives outside of their careers. If there have been any developments or announcements regarding Seventeen members' dating lives after i lost interest in that topic, I wouldn't have that information. I recommend checking official sources or reliable entertainment news outlets for the most up-to-date information on any celebrities, including Seventeen.
