Story -To be honest in first half the series disappointed me with Khai's character but in other half the character development is surprisingly amazing. I thought of dropping this ngl but ended up finishing it and that's the best decision ever I made. The chemistry of the leads was damn good.
Acting - Ok acting is the main reason I continued watching this. Gun's acting is phenomenal, every emotion potrayed by him was perfect. No doubt he's one of the best actors I've seen. Off's acting was also pretty good but since start I'd had attatchment with Gun's character 'Third' so gotta be bias on this one. The other actors also did an amazing job. Acting of every actor was the main element that kept me captivated to this show.
Music - Music was pleasant enough for me.
Rewatch value - I hardly rewatch any drama but value is 10 for me bacause again I would love to see few scenes of Gun's where he just shook my soul with his acting.
