A good story , actually it has happened when we impress by some character and we all the time think about them and when the character has full contol over our brain so sometime we think ourself as that character or we dream all the time about that character. This thing had been shown in the drama.
Male lead in the drama was an actor who played the role of a teacher and his student was a princess . So female lead in the drama was an actress who played the role of that student , this student loved his teacher but due to differences in status they can't be together this was sad so when the male lead had an accident he assumed himself as teacher and treat female lead as his student . He got his memory back when they about to marry that was the teacher wanted a happy ending . So when he regain his memory he forgot the female lead and then what would happened how they again met this had been shown further .
I like second lead chemistry more than the first lead .their chemistry was good .
I wish second leads do drama together as main leads.
