QuoteIn response to the circulating rumors, a representative of LOONA's agency told media outlets, "The dating rumors are completely false. They have no personal acquaintance whatsoever. The photo captured during the 'V Live' was an image of HeeJin's cousin."
People are wondering about the password, which wasn't addressed (and allegedly Gowon revealed the password earlier this year and it is Woo Jinyoung's birthday), about why she would have the pic of her cousin's foot saved on the company iPad that is being used for lives exclusively by more than just her, why BBC is claiming that the girls share iPads when recently they posed with almost everyone holding their own, and whether WJY is the guy Yeojin was seen with in some random streamer's live a while back (? idk).
It's a bit of a ridiculous explanation, but at the same time it's also so random that it could be true. Guys do send pics like this to their friends/gfs/cousins/etc.
