"I'm a solo" 10th Young-sook (pseudonym) answered fans' questions. Young Sook had a 'Ask Anything' time with fans through SNS on November 14th. Young-sook was asked, "When did you prepare for the Official?" The fan said, "I'm going to study, is it okay? How did you study?" "I had a lot of fun until the third year of college, and then I took a year off and studied in earnest. From January, I was announced to pass the final November. At that time, the competition rate was quite high." "I didn't have a smartphone because I was in '05, and I don't have access to the Internet or TV, and I don't see my friends, and my boyfriend sends me to the military," he said. "I remember studying from morning to night like that. If I had studied for the CSAT, I would have gone to Seoul National University," he added with a smile. Young-suk said, "I think I have studied only because I think that if I invest only one year in my life, my job will be guaranteed for a lifetime. If anything is clear and the goal is clear, I will be able to pass it quickly if I run away with only one place in my youth. " On the other hand, Young Sook appeared on SBS Plus and ENA PLAY performing 'I Solo'. Young-sook is 40 years old and is a sixth-grade Official. She married twice in her mid-20s and early 30s, respectively, but suffered a divorce.
