Not scary as in ghosts, but scary as in the crime topic that was focused on. The whole rape and murder crime was really hard to watch. I have to skip a few parts because it's the same scene repeating. I watched this whole show without English sub, except for the first 2 episodes. I can understand a little bit, but correct me if I'm wrong on any of my points.

Story: The story/plot was really good. It was going at a good pace, no unnecessary scenes. By episode 3 or 4, everybody already know that Belle is a ghost. Good comedy and horror that balance out the show. I really enjoyed the scenes where Belle haunt the people in the mansion and some of them decides to start an argument with her. Lol. I just don't understand how Piangruk can't tell that Belle is a ghost and have to prove it. But, with her being able to see ghosts is really cool. I always suspect that Belle's corpse have to be at the mansion where everyone was staying and I always thought that the corpse is in Belle's room. Turned out it was in Piangruk's room before it got renovated. It's scary how the criminals hid her inside the wall like I would've never thought to search there.
Acting/Cast: Everybody was great in their role from main cast to supporting cast. Especially Plengkwan, I think she's perfect as Belle. She can be cute and scary at the same time. Piangruk is a person who can see ghosts and will help them get reborn if the soul is willing to. I really like Piangruk, but I'm so annoyed that whenever she wonders about what happened to Belle, she will always go ask Belle like Belle will not do anything to her. Piangruk will always go to Belle that's why Belle was able to use her body to spend time with Guy. Belle is so pitiful. She doesn't deserve what happened to her. Nobody does. But, she was able to get revenge, but if she's filled with rage and revenge, she wouldn't be able to reborn. Daonuer helped her get out of that cycle of revenge with her final victim, Win. Guy is truly a lovable person. I know he really love Belle, but ghost and human cannot be together. I understand why he fell in love with Piangruk again. She was always there for them. She comfort Guy when he was in distress and tried to help Belle get reborn. I honestly think that Police Officer, Muat Jame (I think that's his name) should be part of the main cast too. If it weren't for him, they would've never know who the bad people are. He never give up on finding Belle's corpse and catching the bad people. I also really like how he believes in ghosts despite being a police officer and not based everything on scientific evidence or research. I also have a feeling that he has a little crush on Piangruk. Win is pitiful as well. If his mother haven't treated him badly and his father have not abused him, he probably wouldn't go this far. But, I remembered Piangruk telling Guy that Win's mother, Piangruk's aunt, got raped. Probably one of the reason why his mother never loved him and for him to act this way. Every action has a reason.
Music: The music sounds good, but don't really match the scenes. It's forgetful.

Overall, this lakorn is well written, a little heavy on the crime scenes, but still watchable if you're strong enough to handle the scenes. Lol. I will probably rewatch it, because it's entertaining, scary, and funny at the same time.
