One thing can definitely be said from the start and that is that this drama isn't for everyone. The story is told very slowly and could have been completed after 8 episodes.
In any case, it's positive that this drama is very close to reality. So problems and decisions that you and I could have made too. Love can be very complicated sometimes. The actors did an excellent job.
However, the story stuttered and nothing exciting happened. The reasons for the roles were sometimes no longer understandable. The ending was a disaster for me.
You basically wait for nothing.
