I don't want to write too much. Just this series should be watched and seen. It's great in every way.
The acting, plot, ost and most importantly the chemistry of the couple was great.
When I saw the teaser, it caught my attention and it was worth watching. There aren't many series with different subjects in Thai dramas, but 'Spare Me Your Mercy' is one of the best in this category. If you've watched 'Manner of Death', you'll like this one too.

I hope there will be a second season or we can see this couple again in another production.
