[Hanahaki Disease (warning: plant Gore), Gravity Falls + Rev Falls + Eddsworld Au, BillDip, WillDip, TomTord, and possible EddMatt]
After the failure of the Pines family world domination, Mason finally opened his eyes to see something he'd been denying for so long. He had even hid it from himself.
He was hurting the one thing he loved. He looked in the mirror, at his birthmarks, in his eyes. Regret sinks in. Will may never forgive him...
He just wanted to protect him...
Silently, while Will was still in hiding, Mason ran away from home in the dead of night. Leaving nothing but a blue petal, from his own midnight rose.
...
In the town next over, Gravity Falls, Bill watched Dipper nervously. He knew he had to say something, and soon... But what?
But then, thoughts about Weirdmaggedon caught his attention. He was concerned. What if...
What if Dipper really did hate him?
Overthinking it, he soon teleported away, leaving a golden dandelion petal on the floor for Dipper to find.
...
The two fled to Brittain on different paths. There, they sought the help of a famous doctor. However, they had no luck.
Not long after the pair met each other, they met a brown haired guy in a blue hoodie at a bar. The guy had cherry blossoms growing out of his eye sockets, blocking his vision at some points.
After a bit of Smirnoff, the man introduced himself as Tom. He, too, was a victim of the Hanahaki Disease. His worst enemy rejected him blatantly... Not a fun way to go.
Luckily, Tom knew of a good local alternative. But, when they left the bar, Tom noticed Tord outside, and accidentally made himself known to the man that caused this problem by staring too long.
At the same time, for the very first time, Mason got a phone call. It was Mabel and Will... He picked up.
