DAY6 member Do-un (real name Yoon Do-un) has reignited dating rumors with influencer Yu Ji-yu. When the first dating rumor emerged last month, his agency JYP Entertainment denied it as 'baseless,' but new evidence has surfaced, causing disappointment among fans. The issue stems from a vlog video uploaded about 8 months ago on Yu Ji-yu's YouTube channel, showing her dining at a collaborative limited-edition event venue between Lotte Hotel's Chinese restaurant 'Dorim' and DAY6's 10th anniversary celebration. The table in the venue clearly displayed 'My day' (the fandom name) and 'Day6' text, and this collaborative course was so difficult to reserve that fans camped out overnight trying to obtain cancellation tickets. Previously last month, evidence such as spotting a pet in a vehicle, similar home interiors, shared plants, couple keyrings, and phone stickers sparked the initial dating rumor. Fans are responding coldly, saying 'they openly dated at the commemorative restaurant filled with memories of fans and deceived us by recording it on video.' Meanwhile, some caution against 'hasty interpretation,' suggesting it could have been a simple visit with acquaintances.
