Prepare the rice: Break up cold, day-old rice with a fork so there are no clumps.
Cook the bacon: Heat oil in a large frying pan or wok over medium heat. Add bacon and cook until golden and crisp.
Add garlic and kimchi: Stir in garlic and cook for 30 seconds, then add kimchi. Fry for 2–3 minutes until fragrant and slightly caramelised.
Build the flavour base: Add gochujang, soy sauce, sugar, and kimchi juice (if using). Stir to coat evenly.
Add the rice: Increase heat to medium-high. Add rice and toss for 3–4 minutes, pressing with your spatula until evenly coated and slightly toasted.
Fry the eggs: In a separate small frying pan, fry eggs sunny-side up until whites are set and yolks are runny.
Finish and serve: Drizzle sesame oil over the rice and toss. Spoon into bowls, top with fried eggs, spring onion, sesame seeds, and extra kimchi.
