This drama is a remake of 'One Night Spring ' which was an outstanding drama.

I started this drama with good expectations but it completely lacks the warmth compared to the original, which is why it comes off as implying blatant cheating which is the fact in most cases.
They did edit the script only to create more flaws.
Now it's a drama about emotional instability and indecisiveness rather than taking the right path.
I somehow couldn't support both leads.

And the ML is stone-faced, bad casting IMO.
Yes, the character does demand a bit of coldness but there's a difference.
Anyway
It's not the best of the remakes but anyone who hasn't seen the original may want to watch this, but you shouldn't tbh.
It's below average and doesn't do justice to the original script, why ruin your idea about a plot that hasn't lived up to the potential as a remake?
I dropped it at EP 7.

You better watch the original if you haven't.
