The recruit from Blue Tower has passed away

'Blue Tower' actor Lee Yong-ju has passed away at the age of 44.
It is said that he passed away from a heart attack due to a worsening pre-existing condition.
I watched 'Blue Tower' quite often on YouTube and even saw it recently, so this is very sad.
Because of his role in the show, I always thought of him as being so young, but heart disease is truly terrifying.
May he rest in peace.
