EXO's Suho and Sehun guested on the November 6 airing of 'Hello Counselor'.

One of the concerns on this week's episode regarded a teenager and his mother. The teen claimed he's often put in an embarrassing situation due to his mom, who's too straightforward with education, saying things such as, "Too much ion is bad for your body", and "Make sure to wash your hands before ing."

The MCs asked the teen, "How is ion bad for you according to your mom?" He replied, "She didn't tell me that." The MCs then turned to Suho and teasingly asked, "Suho, how's it bad?"

The idol brought laughter as he answered, "Well, first, it can make your bones weak..." The MCs laughingly responded, "Old folks used to say that in the past."

Suho continued, "I'm just kidding. (It's bad because) it takes your concentration away from studying." MC Shin Dong Yup commented, "Yeah, your bones turning weak does not make any sense." He then grabbed Suho's arms and yelled, "See, see, it's not weak at all."
