Gather all ingredients and set the oven broiler to high.
In a large pot with boiling water, season the water generously with salt. Add pasta and cook until near al dente (just a touch under) according to package instructions. Reserve some pasta cooking water.
Spread cherry tomatoes on a baking sheet lined with foil. Broil for 3-4 minutes until burst, remove from oven and set aside.
Pat scallops and shrimps dry with paper towel, sprinkle both sides with salt and pepper. In a pan over medium high heat, add oil and when it's sizzling hot, add scallops. Leave them untouched and sear for 2-4 minutes until the bottom is brown (amount of time depends on size). Flip and sear the other side for 1-2 minutes until brown. Transfer to a plate.
Add some more oil to the pan if needed. Add shrimps and sear for 1-1 1/2 minutes until the outside is no longer pink and shrimps are almost cooked through. Transfer to the same plate with scallops.
Reduce heat to medium, add some more oil to the pan and then add garlic. Sauté for a few seconds until fragrant and then add white wine. Deglaze the pan and let it cook for about 20 seconds. Add cherry tomatoes, pasta, butter, shrimps and scallops along with any juice on the plate. Mix thoroughly until butter is melted and flavors are combined. If the pasta is too dry, adjust with some reserved pasta water. Season with salt and pepper to taste.
Transfer to serving plates. Sprinkle parsley on top and serve immediately.
