VIXX’s members have always been close and supportive of each other, and they proved their strong bond yet again as Hyuk recently went to cheer on his fellow member Leo’s solo activities.

Leo made his solo debut last month with his title track “Touch & Sketch” and has been busy with promotional activities. His performance on “Music Core” on August 18 marked his last music show appearance for the song and the group’s youngest member made sure he was there to show his support.

Hyuk uploaded photos from his visit to “Music Core” with the teasing caption, “It’s hard being the youngest and looking out for the older members.” He also included a look at the sweet letter Leo penned for him. Leo wrote, “To our pretty Hyuk. I see that you really wanted to see me so badly. I really missed you too. My dongsaeng (younger brother), don’t be sick and let’s always be together. I love you.”

VIXX’s official Twitter account shared more photos of Leo and Hyuk as well.
