the story highlights one thing.. when men like us fall in love..(not lust or any other perverse thoughts).. we give everything without thinking.. e.g. rationally.. he could have just give one eye.. but altruristically, love might have blinded him.. He didn't give here just one eye cuz he felt responsible and wanted her to live a normal like which would be without him .

Watch the original Korean video, with all the extras in it. VERY moving...
