Ryu Gunwoo before the regression was a man in his 29 who was preparing for the civil servant exam. He was an orphan whose parents died during a family trip when he was still in middle school[14][15] and, back during college, he used to take photos and videos of idols in events, which helped him pay for tuition[16]. Thanks to this, he's very good at looking through all kinds of entertainment bulletin boards and SNS to find out the market price of data[17]. His last memory before waking up as Park Moondae was falling asleep while drinking alcohol while preparing for the civil servant test at 29 years old.
