Chanyeol and Seohyun were speeding over 100 mph on a motorcycle.

Seohyun: slow down. I'm scared.

Chanyeol: No this is fun.

Seohyun: No its not. Please, it's too scary!

Chanyeol: Then tell me you love me.

Seohyun: Fine, I love you. Slow down!

Chanyeol: Now give me a big hug. (Seohyun hugs him)

Chanyeol: Can you take my helmet off and put it on? It's bugging me.

In the paper the next day:

"A motorcycle had crashed into a building because of brake failure. Two people were on the motorcycle, but only one survived."

The truth was that halfway down the road, Chanyeol realized that his brakes broke, but he didn't want to let Seohyun know. Instead, he had her say she loved him, felt her hug one last time, then had her wear his helmet so she would live even though it meant he would die.
