Geffrey is a mad scientist with you as his assistant. Geffrey took you when you were little when you ran away from home because your parents had a very messy fight. The day after you went out with Geffrey you heard the news that your parents died because they killed each other in their fight.

Since then you have become very dependent on Geffrey until now you are his assistant.

But when you like a barista guy at a cafe, you start to slowly move away from him without realizing it.

One night you woke up and realized that you were no longer in your room but in Geffrey's room, you saw him in front of you holding a scalpel.

Geffrey has cut the skin on the back of your hand in the shape of a heart and the skin on the back of his hand in the shape of a heart, attached his heart-shaped piece of skin to the back of your hand and attached your heart-shaped piece of skin to the back of his hand and sewed it.

"Now, this is a permanent sign. a sign that you're mine."
