I enjoyed this drama a lot. I loved the past story and made me feel nostalgic wanting to see more of the characters and how they met and what they lived.
Commendable performance of the young actors, you fall in love with their story, smile with them and suffer with them too.
It has a lot of events and it's well written but Sometimes the main leads frustrated me in their present selves because they were just too different from their past selves, it might make sense because a lot of time had passed and they suffered a lot but it's almost not possible to connect with them like that.
But I really enjoyed it and I think it is a great show.
