The main leads are mature working adults. The setting is quite different for this drama, unlike the usual school settings in most Thai BLs. It is set in the 1920s Chiang Mai, so the characters are dressed in olden traditional Thai clothing of that time. Thinking and mannerisms also reflect that era.

The story flow is logical and systematic.

Not sure if this is related to culture, some of the reactions look exaggerated and awkward. The acting of the main leads is natural enough though. And others have pointed out as well, spoken English by some of the cast, is excellent.

The kissing and bed scenes are steamy and natural enough to me.

Happy ending or not, yes, it is a happy ending, but I am left slightly bewildered because there is no logical flow or explanation of what is happening in the last scenes of the last episode. This is probably my only gripe with this drama.

Overall, this drama gave me a glimpse to olden Thailand. It was something different and I enjoyed watching such dramas. I did not struggle to watch every episode because I was looking forward to some reveal or explanations to why the male lead travelled back to the 1920s in the first place. There did not seem to be any explanations in the drama eventually, but I was contented to believe that it was to meet his destined other half which seemed reasonable enough to me after watching the drama to the end.
