When I was 18, I loved boy group "BTOB". And they held on their concert in winter season. My friend's friend, in other word, an acquaintance got two tickets and looked for a person who goes with her. She already knew that I loved BTOB and she suggested me to go to the concert. I really hoped to go there, but I thought it was very important period to study and I didn't have confidence to persuade my parents. So I gave up to go there and just waited next concert after entering a university. But there were no concert after entering a university because one of members went to the military. I really regretted those choice in that time.

Hi, Megan^^
Thank you for sharing.
You must've felt really bad. 
It was like the only chance you had to attend their concert.
