Yoochun always disliked his trainee days. It wasn’t the dancing, the singing, or the other trainees. It was Lee Sooman.

That old son of a was always making life hell for Yoochun in the weirdest of ways.

The thing was that Lee Sooman fancied Jaejoong and he used Yoochun to get to him. For example, whenever it was time to leave the studio, Lee Sooman would always sneak up behind Yoochun, give him a good scare and then tell him ways to get Jaejoong to like him. Some were stupid, some were weird while some were just wrong and disgusting. And of course there was a lot of ual favours to be rewarded with if Yoochun succeeded. But since Yoochun had no interest in getting dirty with the maan in charge of his career, he never did what he was told.

Therefore, Yoochun got those ual favours whether he liked them or not because what Lee Sooman wants, Lee Sooman gets. But in the end, Yoochun rather liked y time with the idiot Sooman and that was why he hated it.

So basically, Yoochun had to go through his trainee days being a addict.
