Duke,
I think I read a different story.  I acknowledge the fact that things look different through different eyes.

high skilled laborers (workers?), fell in love ( maybe) , got married ( not with the girl they wanted). got bored of relationship ( don't know yet), all characters living pretty much same life...da da.da... ( what to take from this meticulously built up  detail of each character? You can summarize the characters and take the average value or wander around with the variance.)  definitely can relate(yes, nothing unnatural).
 just an immigrant story for skilled labor. [ most of the characters are immigrant and they work. However, relationships, compromises, Nepali social structure and many other issues are prominent and conspicuous than immigration  in the plot.]
 where is  the twist; is it coming ? ( I can't say)  how about a brother or sister or a new  character or a friend who brings something else to the table ? ( If the story ends here with some concluding statements from the author, I will accept it as a story about lost love and the pungent feeling that last throughout your life. Many people live with that qualm of missed connection.)

 It was a good read, very spontaneous, keeps u curios ..but if you u step aside and think about it. - what is the point ? (point is ..... it keeps you curious, it is good read and very spontaneous..  just kidding. If you read between the lines you can see through the author's mind. he is saying a lot through his characters, isn't he? many simple things in life are so beautiful and meaningful, when said with right words, win you. I am sold.  )

Cerine, your bore-ology was impressive.
