This was my first time watching something that was 50+ epsisodes long, my previous longest drama being 28. But im really glad I gave this a go, loved the characters and enjoyed the story for the most part (very long melodrama section in the mid 30 to mid 40 epsidodes), but in fairness that was more me binging rather than watching on a weekly basis.
So in summary dont let the length of this drama discourage you.
7.3 come on, it's better than that. I think its misunderstood, the ML only wants the FL to do more and get more from life, yes she's ditzy but they are ditzy people in the world and he accepted her without question.
Some genuinely funny moments and sweet moments. But for me it suffered the dredded time slip cliche, (gone for months or years, but come back and act as if they left yesterday) hate it really hate it.
The writing wasn't as slick at the end as it was at the beginning (the change in writer showed), but overall still a good drama and glad to see they wrapped the story up.
So in summary dont let the length of this drama discourage you.
Don't let this slip you bye.
Though I did enjoy the last episode.
