These dramas follow the journey of a young man who take on the responsibility of raising a toddler on their own. They struggle to find work balance and a proper comprehension of a child's heart and mind. Yet through the ups and downs they persist and grow as loving fathers.
I know there aren't many similarities between the two(in terms of plot) but if you like a drama that deals (or at least partly deals! with the relationship between a father and his newly found daughter like "My girl" you'll probably like "Oh my lady". Both are great dramas and you won't regret spending time to watch them! :) ( and there's also siwon;)
