I am not so sure if there was any drama with such an ending that makes me feel happy and sad at the same time.
I like the fact that the expected end as one sees in the usual was not given as a closing to this drama. In reality, any sensible lady would go for the second male lead. That's a mature mind to really fall in love with. Living in the euphoria of young love as seen between the two main characters is better done in movies than in real life. The ending gives a real picture of how it is in real life.
I'm sad for the main male character but it is what it is, this is the real world.
Great plot, setting and excellent performance by all the leads.
