Pure curiosity of a regular person looking at Winter and Jungkook's dating rumors

Winter seems like a top idol, and Jungkook also seems like a top idol. When dating rumors like this pop up, their respective fandoms denying it and saying 'ignore the dating rumors, don't feed the trolls' is because of: 1. It interferes with fans who engage in 'couple cosplay' (yu-sa yeon-ae). 2. Fans bought stocks in the idols' agencies and are worried about stock prices dropping. 3. It makes them feel insecure when a popular opposite-sex idol is dating someone. Which of these psychological reasons is it?? + They say idols' marketability drops when they date. So, what do fans think is the age or time when idols are allowed to date? + Probably the socially awkward folks will just downvote and run away.
