Jonghyun cleared up what he really meant in an earlier interview.

The interview for Nylon with SHINee was revealed earlier today, where he was asked, "What do you especially regret?". He answered, "Dropping out. I don't think it was that great to drop out of high school to go to the music school. I felt like I was wasting my time studying back then, but now that I look back on it, I don't think it had to be like that. But still, it's not that I have a lot of regret and feel guilty."

After he read how his own words came out in the interview, he must have realized that it was open to some misinterpretation. So Jonghyun took to his Twitter to clarify what he really meant by sharing, "Going to Smi (Seoul Music Institute) was the most important turning point in my life, and the best decision. There must have been a miscommunication of some sort. I feel disappointed about it all, but I don't have any regrets."
