It's quite a straightforward premise but the attention to details is simply unbelievable, the plot is really precise from the start till the end, taking audiences onto the journey of a man's last mission. The intention of the protagonist unfolds just like him remembering his past as he latches onto the next target, with action sequences that will blow minds. As always Lee Sung Min never disappoints with his masterful class acting, but the more surprised performance from Nam Joo Hyuk really steals the scene a lot, the chemistry between them works so well it just makes the closing scene highly emotional, exactly like how a bittersweet remembrance should be.
