sunoo is your boyfriend since 2 years, high school sweetheart. It was perfect with him, both each other's first love, first kiss, first everything. Everything was perfect until you got diagnosed with cancer. Sunoo stayed by your side the whole time but he didn't even know how but he fell out of love. He couldn't say it to you, you had a cancer, it will just break you down even more

one day he was with you in your hospital room, laying next to you. You were talking about how you dream about going to Disneyland

"I promise when you'll be healed I'll take you to Disneyland"

a promise he won’t keep
