and remember professor cha's first appearance, he was looking at Jiheon!!!
maybe he's obsessed with Jiheon or Jiheons mother??? because like wdym you met Jiheons mom on germany????
like he's obsessed w Jiheon so he tried to kidnapped him but took wooju in mistake coz wdym the Cha's the one who discovered and help wooju and Jiheon not even in the news when wooju clearly state that it was Jiheon who found him?
AAAAA I'm getting crazy, it's turning a dark turn, I was literally giggling because it was cutesy at first lol
maybe it was professor cha who kidnapped him that's why he has scar on his head? and professor was the one who provided the pills that causes hallucinations
remember that the name of the pill is Honey? and it's Jiheons nickname? does the pill made our babi hallucinates every traumatic events & person turn into Jiheon even though it was not really him?
