A perfect ending! (excluding the convoluted thriller aspect of the narrative)
After watching the final episode, I realized how blind I was to ST's desire to overcome his trauma, considering Episode 1 has a subtitle of "The Boy Who Grew Up on Nightmares" and it was ST who is haunted by the nightmare of butterflies. Drawn to the flashy romance between KT and MY, I was blind to ST's desire and capability to face the unknown and embrace individuality. The narrative ends with ST's first step as an artist and the new couple's first day of a journey together.
