Everything was too easy for Tol initially because he got help from Jinta and Tin (in his dream), but I hope that…
I haven't trusted Jinta since the beginning. Why would a heavenly angel put someone through death timeloop? His reasoning hasn't been explained; it'd be a good plot-twist if he was the one who orchestrated everything for his own amusement.
I don't think he's really the bad guy; he's just not sympathetic and isn't motivated in at his work. He wasn't really the direct cause as to why Rit lost his kidney, but he did play a part in it. Tin was just following what Sak told him to do. However, Tin really doesn't feel bad that handing over Rit as a patient lead him to a kidney.
We still need to see 2 scenes. KimChay slap scene and the KinnPorsche pool scene. I'm guessing maybe the slap is next episode and the pool will be the last maybe?
