Episodes 7-8... Shipping intensifies. :D Ah, no, seriously. Dong Chan and ahjumma are too shippable.
Gosh, there's all the murder stuff going on, sure, but they still manage to have that cutest moving-in scene ever. Awwww. And grandpa. Aww. (Kinda.)
Also, I'm getting so frustrated with Saet Byul going around on her own. And these cliffhangers! Oh gods.
