I'm guessing teacher told izana that he is now free from ghe curse because i remember the curse would only be broken if he wholeheartedly trusted someone (in this case, he did because he still ate the cake that ginger made for him). So i'm guessing teacher was like "you're free from the curse and learned how to wholeheartedly trust someone blah blah blah"

So I checked the raws...
• ML still ate the cake and did not doubt the fl(awww)
• He got poisoned and fell on the floor
• 2nd ML tried to heal him
• Red headed btch(lerazie) blamed Ginger and she cried
• ML was saved when Ginger's tears fell unto his eyes
• ML woke up and Ginger and him were lovey dovey
• Lerazie trembled and was jealous
• Learzie's grandpa(2nd ml's teacher; the red headed old wizard) soul suddenly showed up( i dunno wut he said since i can't read korean)
• He said some things (korean) and vanished and the necklace that was used to prevent the royal family from reading minds also broke in pieces
• Lerazie was arrested
• Ml and FL kissed
• (imma skip this part im too lazy)
• ML had a banquet and Fl changed
• When she went to the banquet King Izana( ML) proposed to her and she accepted it(of course)
• They went to the terrace and talked about some things( in korean)
• ML and FL went to a room ( i dunno whose) and drank wine. They were remindedof the flashback when ML was drunk
• ML is drunk and FL approached ML. When FL approached him ML faced Fl on the floor.
• ML kissed FL on the neck and they spent the night together
