Can You Hear My Heart (2011)

Both are heart warming drama, TWTWB has female lead with blind while CYHMH has male lead with deaf.

Em ambos os dramas tem personagens com surdez e problemas cardíacos. Ambos também mostra o sofrimento para sobreviver a uma doença cardíaca

Both are beautifully made dramas (on all aspects - story, acting, directing) and both are tear jerkers.

These 2 dramas have similar aspects: both MLs are disabled, where ML is blind in Crush and ML is deaf in CYHMH. Both MLs went through childhood hardships and trauma. They seem cold on the outside yet they are actually very warm. FLs are very sweet.

Both are 30 episode makjang melodramas done extremely well. They both have birth secrets, revenge, a lot of heart warming moments, great acting and writing. They are both a lot of fun to watch.

There is also many things are alike you can watch drama it's pretty good and mystical drama I hope you like

There main male lead are most a like and famale lead too working hard and flatter I don't know but I find something about irritated so I stopped to great seducer but you mighty like this drama

Beautiful Gong Shim seems to be comedy/romance with some drama and Can You hear my Heart is drama/romance with some comedy. While Drama/romance with comedy is quite different from Comedy Romance with some drama, but I think you will find both dramas romantic storyline satisfying.
What they have in common is the actor Nam Goong Min playing a lead role that is wrapped in mystery pertaining to his childhood/parents/identity.
