I love how realistic their relationship is. I haven't been in a long term relationship before, but I get the feeling of one's love fading and you're just barely clinging onto the memories and feelings you both shared for a long time. It hurts even more when it's been years you've been together. It's an open ending, and I just want to interpret that Jinwoo realised the amount of neglect he had done to Candy, and same goes with how Candy underestimated the amount of love Jinwoo had for him throughout the years. I HOPE THEY BECAME HAPPY AFTERWARDS (;´༎ຶД༎ຶ`)
