Since senior high school, you and Xain have been in a relationship. The relationship was healthy, and you had never gotten into an argument with him, not even a single one.   Xain invited you to have a picnic at his favorite park. You're confused because it was so sudden because he said he'd been busy studying for his finals this week.   He was sitting on the picnic blanket while you were laying your head down on his lap, admiring the sunset.   "The sunset is beautiful, isn't it, my love?" He showed a smile, hiding the fact that he's feeling so weak. One thing that he has been hiding from you is that he only has three days to leave due to cancer. He doesn't want to tell you because he doesn't want you to worry.
