Park Chorong and Oh Hayoung on Trainee Days
Apink debuted on April 19, 2011, with an EP (Extended Play), Seven Springs of Apink. Both artists shared heartfelt memories and revealed a hidden side of an idol journey – their strict evaluation, financial uncertainty, emotional pressure, and physical exhaustion. The senior idols have revealed something which left behind the glamorous veil that the K-Pop industry has used to highlight. When they entered the training systems, both the idols were very young, and they had to go through a very rigorous training. As in the K-Pop industry, trainees follow a rigid schedule, have to undergo daily evaluations, and often live in dorms.

During the episode, when Donghae said, “You guys haven’t changed at all,” Chorong replied, “Sunbaes haven’t changed either,” keeping the mood lighthearted. Eunhyuk added with a knowing joke, “We only say this among ourselves. When the same generation gathers, we say ‘you’re still the same.’”
When Eunhyuk asked, “Did you follow an extreme diet at the beginning of your debut?”
Hayoung admitted it honestly, “Yes. Back then, we were quite chubby,” sharing the pressure that, to survive in the industry, it’s important for people to maintain a visually appealing presence.
Chorong also explained how the emotional weight of responsibility felt heavy even before debut.
