And then, and then, and then... before she knows it she'll be so deep in that she'll be scoffing at the IG posts digging up old photos of Lee Min-ki because, hello, those she found long ago, when they'd just started airing Because This Life Is Our First, so why aren't any fans bringing forth new stuff. Around then, when she's particularly vulnerable because BTLIOF left a gaping hole in her week, she'll fall into City Hunter and be prepared to overlook her Lee Min-ho discomfort (temporarily), so we must be prepared.
How best can we reduce her to a gibbering wreck in front of her family and friends? How best can we pepper her internal voice with words that nobody understands around her? How do we leave her sobbing at midnight in front of a visibly exasperated husband who doesn't care in the slightest that So Ji-sub reminds her of him in Oh My Venus, especially since she's crying because of Descendants of the Sun and Oh My Venus has not yet been watched.
She will hunt for memes when Goblin is over, and listen to the OST on a continuous loop, so how can we ensure she has enough memes from around the internet to keep her going till she's strong enough for the next drama? How, in short, do we ensure that she survives this year and makes it into 2018 without snapping?
So they made Healer.
That's my theory and I'm sticking to it.
