A simple introduction to the characters, showing how they get along in a forced cohabitation. The acting is good enough to show the basic personalities of each character. The music and sound effects are brief but specific to a scene or reaction respectively. The dialogue is relaxed, like two teen young male adults who don't know each other well might have with each other. I think the less said lends to the story expected to be told, creating a foundation. There are a few (O.o) moments to feed the BL fan but nothing overt or pushy.
A lot happens in the first episode. Meet Neo who sleeps with the bad guy's wife. Meet Miw who gets paid to sleep with the bad guy's son. Meet Shin who is the bad guy's son. One night, everything goes sideways in the men's room of the strip club where Miw works. The body count starts now.
This is one of those stories that's starts out to scare you in one way, but ends up scaring you in another way entirely. This story turns out well, but let's remember the ones the doll represents.
