I like the only story of the main characters, but their story is too simple that and less entertaining for others.The story about the teacher and student makes me skip those.As if the main cast is the story of the student and teacher relationship, because most of the scene are more focused on them.I wish the main couple had more scene to made the whole drama better.I watched the whole drama and re-watched only the main couple scene.The ending is good because all of the bad things were brought out in the open to make the whole story happy for the main couple.
