First of all, this series has got a very good plot with truely amazing ambition. A smart and talented, yet, untrained heir of the biggest business in Thai living in solitude within the social envy for him while facing the loss of dear family members and running away from hitmen, while meeting the love of his life. I bet you can't find another one like this.
However, there are minor to apparent plot holes that happened:
First, Where is Ma Mam's employees when she was shot ? It's a hostel, the employees were supposed to be there since early morning, therefore, she wouldn't have died from a gun shot. And, Her wound was in the stomach, how can you physiologically die from that in such a short amount of time ?
Next up, how did Neung found out his uncle's plans and the uncle's son's involvement when he had just got back ? Did he receive a message from the universe ? I don't think so.
And lastly, where were Neung's abundantly hired bodyguards in the last ep ? They could have saved Palm's a bullet, I guess Neung had ran out of money before the event happened.
So as you can see, many plot holes.
In addition, the 2 main actors did not deliver persuasive tears during sad scenes. They looked like they were laying eggs instead of crying. But you know what, they're one of my favorite BL couples out there so I can let it slides. On the other hand, the supporting characters did a wonderful job. They fulfilled their missions of conveying the emotions to the audiences, especially the actor who played Neung's uncle/Chopper's dad. There were no scenes in which he appeared that didn't make me mad, which is the best thing that he had done playing the villain. I praise him.
Nevertheless, I enjoy the copyrighted soundtracks the inserted into the series, It support the atmosphere extremely well. The OSTs however, there was only the Pond's soundtrack that was impressive.
To conclude, this series had room to be made better. But not at all bad or unworthy of you time. If you are not a detailed person, you would surely enjoy this series.
