That's why I think they chose the right person as Sila. He is a complex character and his emotions are raw usually it's very transparent with his eyes.I've started rewatching from Episode 1 (with no need for these 20/21/22/23/24 excruciating waits! hehe) and the magic is happening all over again. Everything seems more poignant when you're not watching it in a rush. From the start when we're introduced to Sila you can sense he's a loner - even if surrounded by beautiful women at his club, it seems his wont to always end the evening drinking alone, reliving his tortured memories of the past. The child actors played Min & Sila so beautifully, there's always an aura of sadness in that friendship. A togetherness yes, but not happiness; that's why I enjoyed Episode 1 very much, they've met again & there'll be feelings of a different sort between them! I feel to stop the missing we can always relive the episodes in our own ways; we can find avenues to always stay in their world.
Sila is a lonely man...in more ways than one.
