What is the secret to BTOB's long-term success, according to Eunkwang?!!!

It's the youngest, Seongjae! lol
Sungjae was really, really busy in the early days of BTOB~~
Back then, we filmed dramas and even 'We Got Married,' which was a hot topic at the time, and worked so hard to promote the group that we barely got any sleep...
Since Eunkwang is also aware of Sungjae's efforts,
They say they will monitor all the videos of Sungjae's solo activities.
Seongjae was also grateful for this kind of point! ㅜㅜ Even though he might have only known about it superficially or just seen it in passing
You said it gives you great strength when someone makes sure to mention that you enjoyed the show.
Eunkwang is so proud of the maknae for working so hard lol
I guess thanking and supporting each other is the secret to BTOB's longevity hahaha.
