Mason lied to his boyfriend.
That call was fake.
His dad has already called him when they both were at home and didn't call him again at the clinic.
Even that conversation on the ohone was just an act.
He knows that lying to Matthew is fucked up but he had to.
Mason parked his car in front of his house before rushing to the trunk and take everything he bought on the way before running inside the house.
All the pictures that he took of him and Matthew, he made them into an album that they can keep together and fill it with more pictures later.
He quickly opened his bedroom door and walked inside.
An excited smile appeared on his face when he noticed how great his work is.
There was small yellow light bulb around the room, Matthew's favorite flowers everywhere.
The album was right on the bed that was filled with petals.
He even prepared the bathtub for them later.
