I have been postponing watching this series since .. before it is released ..
Why ? Because I could not get over ArhitxKongpob (main reason) and FramexBook (secondary reason)
Although I have watch other BL's with different pair, ArhitxKongpob is one that leaves a very strong impression on me.

I also feel rather sceptical when I read the summary, a ghost and a human?
What are the possibilities of a 'happy ending'? Transmigration? Reincarnation? Both doesn't sounds very appealing to me ..

So, finally I muster up my will to watch them, and I SHOULD HAVE WATCH THEM EARLIER ><

Story-wise, the development of the romance is SLOW .. yes .. really really SLOW
Perhaps my bias, I have been waiting for the relationship to develop, but it is SLOW ..
and the 'catalyst' of the development of relationship, is not something that I would horray on, but the delivery is acceptable .. (not the annoying type)

I love how they address the issue of Than's uncertainty regarding his feelings / orientation ..
The coming out scenes, well I love how he comes out to his mom ! It's a tearjerker for me ..
Hoorah to Than's Mom !

As a romance series, I would say they did a pretty good job.
HOWEVER .. If you come for the 'mystery', or 'detective-ish' ones, you won't get much out of this series..
I don't feel the unfolding of mystery is well prepared .. and how everyone is connected to everyone .. It's odd in a way ?
The revelation of truth, seems to be a bit, forced (?)

The ending of the series .. well ..
It's, what I would say, not actually a conclusive ones (?)
But I think that it is the best possible option for us now ..

Overall, this series is a good watch, and not draggy

PS: If you have extra time, I would really recommend you to read the novel too !
