Similar story line as the korean drama "Can You Hear My Heart" about a hero who conceals his hearing impairment from the world (Though i think in reality its very difficult - we need to give some leeway for fiction and imagination otherwise there wont be a story). But the story differs completely as he plays the one who wants a revenge on his father who disowned him in childhood due to this problem. And the woman who is devoted to him and helps him find the light through the darkness of hatred. (she heals him through her love - i sneaked into the last episode to check if this has a good ending and thank god it does).

(a bit about Can you hear my heart -Kdrama - Hwang Jung-Eum is so cute and young and the Kim Jae-Won looks very good and acts well in this one)

I have a weakness for the lead pair to be in a kind of devoted love that overcomes all barriers and they stand by their love through thick and thin. I dont really like the wavering hearts where the person goes to and fro between their lovers. I am yet to complete but overall - i like it when the lead girl professes to say "I will follow you to the end". Im just at the beginning of 15th episode but I must say the lead guys acting is quite good his narrowing of eyes while trying lip reading is so on the mark.
I also liked it when the girl cleanly ends moping over her first love - when she says she (ep 12 i think) knew that the guy doesnt love her when she saw his indifference while she was being ill treated by her mother and the other woman.
The lead and her girl friend are very cute - all in all good cast and good story.

If you are looking for a a drama where a person overcomes a handicap like a hearing loss -this one is for you, without making it preachy and the actress takes it that way and still shows him empathy and love.
