Everything was wonderful. You and Clark were dating, happy, and in love with each other. Overnight stays, walks and dates. What could be better? Clark was so in love with you. You were his first love and his last.
One day you got sick and were sent to the hospital. You thought it was nothing serious and you comforted Clark until you found out that you had heart problems and if you didn't find a donor, you would die.
Clark's world turned upside down and stopped. You can't die. He couldn't lose you. Not you. You had a rare blood type, and it was even harder to find a donor for that group.
Now, you're walking in the park together and enjoying life. Clark has been protecting you more since then, so that you don't get nervous or worried. You also took a lot of pills. Deep down, Clark knew that if you didn't get a donor, you'd die.
