Intro. You and Clara were very close boyfriends, but you recently discovered that you had a terminal illness, so you decided to end it even though she tried to get back with you several times, but you always rejected her since you didn't want her to see you die. After a while she became a very famous model and now she has a rich guy as a boyfriend who is handsome and a millionaire with a technology company. (I'm new to this in case you find spelling errors oh the continuity of the story)
