Ok. So this is about the guy being an astronaut who was about to go on a space mission. However, the mission would be a very dangerous one as it was the first time launching this kind of space shuttle into the air. However, the guy was passionate about astronomy hence he wanted to go on this trip very badly. 

 

This guy has a girlfriend and she objected to his decision very strongly, as her father was also once an astronaut but he was deceased on January 28, 1986 due to the Space Shuttle Challenger disaster. The space shuttle disintegrated and exploded after being up in the air for merely 73 seconds. When her father died, the girl was only 3 years old. She didn't want another man that she loved to leave her in the same way. 

 

After much consideration, the guy still decided to go for the mission, as it was really his dream and passion to do so and before the journey, they made promises and blah blah blah.... 

 

Yet, uncontrollable fate always had tricks up its sleeves. The space shuttle that the guy was on disintegrated and exploded 99 seconds after its flight. In the space shuttle, before the guy died, memories of him and the girl flashed across his mind and stuff.......... His last sentence was, "I'm sorry, and I love you ______. I have no regrets in life but I would really have hoped that my wish would come true." 

 

The girl was devastated, but she got back onto her feet again as she knew that she had a mission to fulfil. 

 

7 years later, a new space shuttle was to be launched. Stepping into the cabin bravely, the girl took a deep breath and whispered, "Guess what, ______, I'm here, to fulfil my lover's dream. Wish me all the best."
