"MIXNINE" and "SPECTRUM" member Kim Dong-yoon, passes away at the age of 20 years old. Sister announces on SNS.

● My only brother in the world went to heaven. I would be pleased if you would like to make a final greeting. You must be truly, truly, absolutely sure to be happy there.

My brother is tall and cool. I guess jealousy came from heaven. Even so, it is too cruel, he was 20 years old.
