Joining in a lot of the hype and anticipation, I watched the first episode. Honestly, it's okay, I'm not as blown away as I thought I'd be. It seems more like a cdrama or kdrama than a jdrama with all the usual tropes of those countries' dramas. Cold CEO who is actually kind and loving, a childish, naive, bumbling FL, frequent romantic closeups and slowmo... I'll def try to see next few episodes to see if Koi Deep is for me or not.
