On the October 1st episode of KBS 2TV's 'Vitamin,' TEEN TOP members Niel and Chunji were guests for the show and revealed the group's living situation might be less than ideal.

During one segment of the show, the guests had their blood tested. Niel found out that he should be careful of contagious illnesses and that he might be at risk of catching the meningococcal infection.

Niel then said he is going to take precautions particularly when it comes to the cleanliness of TEEN TOP's dorm. "If one of the members catches a cold, the other members also catch the cold in a relay fashion," he explained. "Our dorm has always been dirty so there might be the danger of meningococcal infection."

The doctors on the show said, "Niel definitely understands which vaccines are fit (for him) and which ones are not. There’s a high chance that he will have the initiative to get the adult vaccine."

TEEN TOP is currently promoting their new soft tempo single, "Missing," on various music shows each week.
