L's mask fell off and he fell, too.
On the latest episode of the MBC drama "Ruler: Master of the Mask", peasant Lee Seon (L) and his mask came off.
He claimed he was the king even if Prince Lee Seon (Yoo Seung-ho) appeared dressed as a king but the Queen (Kim Seon-kyeong) and Han Ga-eun (Kim So-hyun) made it clear that he was the fake.
However, Lee Seon yelled, "The person Dae Mok (Heo Joon-ho) chooses is the real king!". Prince Lee Seon managed to convince the subjects when they weren't sure. They put him back on the throne hoping that he will make an antidote that will save them.
