Suspicion (의혹, Uihok) is chapter 38 of the Twelve Nights webtoon.
Physician Ma is able to tend Dan Ah and Won. Heuk Rang fetches Won, but he reports that Baek Ryung was executed because the queen mother got furious upon hearing that the king is missing. Hyun Bin hurriedly goes to see the injured king; upon seeing Won's robes from one of the maidservants, she smells a faint scent of dream flower incense on it. Knowing that the flower only grows in Seo Seo, she hypothesizes that the incident might be Seo Seo's doing. She then orders Ji Ryeon to find Rok Ha.
