Liam when he realizes that you are missing
...
"What's up with you?" Mason asked Liam. Ever since a few days ago Liam had been acting strange.
"Someone's missing." Liam frowns, shaking his head. "I know I always meet someone here, but I can't remember who."
"Do you think it's the ghost riders?" Mason asks.
"Yeah. I think this person was my girlfriend." He racked his brain further.
"Y/n." Mason chimed in. "I don't know why that name came to mind."
"Y/N," Liam repeated. "I need to find her and soon. I'm dying without her."
