Kim Sung Joo: I don’t think being an idol is that great as it seems.

Doojoon: I’ve never regretted becoming an idol. It’s a fun job that I like.

Kim Sung Joo: If you have a son, will you let him be an idol?

Doojoon: I’d never. It’s not that the environment changes gradually - everything changes at once. There’s a lot of dark things that are different from what people see.
