Inspired by How Could You be That Girl I Knew by unforgettabELLE. For this to make any sense, go read that first.
Alya dragged herself out of bed, wanting nothing more than to go back to sleep and play hooky from work. After going through her morning routine as slowly as possible, she got dressed and opened the door, expecting to see Mari making breakfast or something. She knew something was amiss as soon as she heard a guy laughing. As far as she knew, Mari hadn't planned on bringing anyone home that night...so imagine her shock when she opens the door, wholly prepared to kick his ass, when she sees none other than Adrien Agreste sitting across from Mari at the breakfast table. Her jaw hit the floor, and she promptly walked into her bedroom, closed the door, and then walked back out, pinching herself as if to make sure she woke up that morning.
And then he asked her to be his girlfriend. She said yes, of course.
Alya screamed. Joyous screeches, straight from the top of her lungs, filled the room and quickly captured the pair's attention. After twelve years, this could not be happening, right? But it was.
Alya being Alya, she requested all the details of what happened, and Marinette told the whole story, from the encounter at the club to the rooftop dance to the tattoo parlor and how they ended up here.
And just as both Mari and Alya thought it couldn't get any better, he proposed.
They both squealed.
