Picked up a Golden Pickup Truck with a Broken Arm

My name is Wang Xiaosheng, a high school sophomore who is an ordinary flower grower and a chef. Today I was watching the final battle between Gilgamesh and Shirou Emiya. After Gilgamesh had his arm cut off by Shirou Emiya and fell into the black mud, my computer screen suddenly turned into a black hole, and a figure-sized Gilgamesh fell out... Idea: I'm in love with Shining, but he's too popular. What should I do?
