The profile questions ranged from the very basics such as his name, his blood type, his zodiac, and more, to things like his vision, which he revealed to be 0.1 in both eyes. He said, "I first started wearing contact lenses for 'Produce 101'. At first, wearing lenses was very uncomfortable, but now, not wearing them makes me uncomfortable, so I wear them every single day." But when asked what type of glasses he used to wear before contact lenses, Jung Se Woon said, "I actually didn't wear glasses. So if I think about it now, I wonder how I lived so inconveniently back then. What a strange person I was." 

Jung Se Woon's hobbies are working out and cooking, he also named his closest friend, chose Nell's "Time Spent Walking Through Memories" as his favorite song to sing at karaoke, gave himself a 55 out of 100 on his own looks, sent a video message to himself in his thirties, and so much more.
