Could be masterpiece...is another average K-melodrama

Japanese original drama has the cult status for many reasons.
This remake will not, mainly because of one.
The viewers are introduced to every stage of relationship almost with surgical precision, from fascination, hesitation, trust...until destructive, inevitable end. The stage of growth and maturation afterwards on the other hand is almost completly neglected.
Cliche, last minute ending typical for many K-dramas is therefore not credible and rather disappointing.
Would going back to deeply destructive relationship be happy ending for anyone?
