On the July 3rd episode of JTBC's 'Knowing Brothers', the veteran idol group appeared as a guest. The group talked about how they are known as the 'Idol group whose members all finished their military service' and their episodes related to mandatory military service.
Taecyeon and Junho then revealed their extreme weight gains during their military service. Junho first opened up about his 16 kg(about 35.2 lbs) weight gain. He said he ate too well and weighed 86kg during his military service. He also said Nichkhun couldn't recognize him when he came to pick him up.
