To accept this series, you have to buy into its core belief or concept. This core belief was a functionally based condition that I simply could not wrap my head around either logically or scientifically. Apparently, for some individuals with ‘sudden sensorineural hearing loss’ when it rained, you lost your ability to hear but could still communicate and hear your ‘soulmate’. While I am all for ‘poetic license’, this was carrying something real so farfetched that it simply is not believable whatsoever. Even if it were remotely possible as a medical condition, you would not suddenly develop it nor suddenly lose it as the series implies. I am all for ‘fantasy’ but this one I had a hard time wrapping my head around. Even as a good story. And therefore, I could not. So, I stopped trying.
The true issue here is the lack of communication, not some misused medical condition that sounds fanciful. Not a particularly good or interesting series except for the character of Lomfon.
