It was underwhelming. I am a sucker for happy endings, but here I wouldn't mind if they stayed broken up in the end.
Having said that, the chemistry between the two actors is undeniable, their acting is top notch, the story just feels too rushed towards the end. Maybe 2 more eps would have helped? There needed to be a growth shown for the FL's character. We accept that she is flawed, we want her to succeed, we root for her. The ML too, he is right in his ways, he is strong and goes for his goals, and achieves them, but he is a doormat when it comes to his feelings for the FL. He can't think straight and is completely blind in love.
They both have flaws, it makes sense that they come together and stay together.. We just need a little more justification as to why they choose to do this in the end.
