If you were to ask if you should watch it - Yes.
From a light hearted BL standpoint with a good plot, this drama does justice. It was cute as well as a little emotional. But they put so much on the plate that you wanted to taste it all but couldn't.
For a 8x15 episodes, it was enjoyable and a great one time watch. It showed how you want something and are scared that it might become an obsession. But the heart wants what it wants. I wished they worked more on how they differentiated between love (and need) and obsession.
The story had potential to be a good 16 episode drama. There was a supernatural element and a mystery element with gay romance, side bromance and a traditional family.
But it was like we got a little bit of everything but were left craving for more (but not in a good way).
Without spoiling, I'd say that if you're adding a mystery, provide some closure to it. The romance and co-dependency element of the leads was done okay, but there was so much more that could have been developed in terms of how they come in terms with their feelings (I conclude that they both settled that their exclusive need for the other person is love) and also, I wished for a some more details about the side characters.
