I'm watching ep 371 of Running Man, and it's the one where they have to figure out who is lying and who is telling the truth between Kwang Soo and So Min.
Idk if they're just pretending for TV, but it's very obvious when KS is telling the truth??? They've known each other for so long, they must know that? And yet they seem to doubt him all the time. He always talks more when he's telling the truth, because nobody believes him when he IS telling the truth. When he's lying he tries to play it cool and doesn't say as much to avoid suspicion but it makes it obvious he's lying when he does that. Or he'll fail to keep himself from smiling and walk away/change the subject.
