BTOB's Changsub sought the help of a specialist for some of his latest troubles, with a new video from 'Piki Pictures'!

After choosing the nail art style he wanted done - the Pororo style - from his nail artist/counselor Dr. Da Eun, Changsub confessed, "I have a close dongsaeng... who makes fun of me all the time for being ugly and short... what should I do?" Dr. Da Eun answered, "Tell them to stop," but Changsub argued, "Even if I tell him not to, he won't listen to me." 

Dr. Da Eun then personally demonstrated the best way to stop someone from bullying(?), with a puppy face full of aegyo. Changsub immediately copied Dr. Da Eun's method and said, "Sungjae, please stop buyllying me~". 

In addition, Changsub asked, "How can I get people to laugh when they see me?", and Dr. Da Eun advised making comical facial expressions, the effects showing up right away. Changsub's 3rd question went, "I have a lot of time that I spend alone these days. When you're bored, how do you entertain yourself?" Dr. Da Eun suggested, "Draw pictures, sing, and play with dolls". 

Finally, Changsub showcased a timid side and said, "When I'm somewhere with a lot of people, I get very shy. How can I grow closer to my friends around me?" Dr. Da Eun arrived at a simple solution - just tell them "I love you!"
