A Detective Game, but I'm Trapped in a Love Triangle

Xin Xian transmigrated into a perilous world based on a crime-investigation game, only to get bound to a System that made everyone fall for her. System: I will find the most compatible high-quality men for you, arrange the most romantic chance encounters, and turn you into someone everyone loves! And so... Running late for work, she rounded a corner and crashed into a handsome man. To her surprise, he called her by name and said he was her childhood friend, whom she hadn't seen in years. Caught in a sudden downpour during a mission, she was soaked through and forced to squeeze into a cramped space with her archenemy, whom she couldn't stand. One moment, her perpetually stern-faced boss was scolding her until she was on the verge of a breakdown. The next, she slipped and kissed him right on the lips. Xin Xian: Look me in the eye and tell me again, what kind of game is this? I want to file a complaint! System (looking away): Ding! Affection +99. Use it to draw cards and items! There were all kinds of cards and items: the [Heart-Pounding Compass] led her to the person on her mind, the [Truth Serum Capsule] made someone answer her questions with 100% honesty, and the [Affection Spray] brought her closer to her target for a short time. There were also the [Empathy Camera], [Mood Magnifying Glass], [Time-Stopping Pocket Watch]... Xin Xian's eyes lit up, and she took back her complaint. With the [Heart-Pounding Compass], she quickly tracked down a criminal who had gone undercover in the crowd. With the [Truth Serum Capsule], she immediately figured out that an apparently honest witness wasn't telling the truth. With the [Affection Spray], she quickly blended in with the onlookers at a crime scene and gathered plenty of information from them. Years later, Xin Xian had gone from an unknown trainee officer to a renowned "detective" who cracked one unusual case after another. After an awards ceremony, a group of rookies crowded around her, begging her to share her secrets to solving cases. After a long moment's thought, Xin Xian solemnly offered her advice: "When you're running late for work, try taking routes with lots of corners. And never bring an umbrella when you go out on a rainy day." "Oh, and don't forget to chew a piece of gum before your boss calls you into the office to chew you out." Everyone: ? * Crime-solving mastermind and beloved heartthrob vs. Straight-talking, secretly soft-hearted, stern-faced boss + irreverent archenemy + mysterious, scheming, black-hearted childhood friend + ?? Reader's Guide: 1. The setting is very loosely constructed. Everything is there to serve the plot, so please don't compare it to real life. 2. Crime-solving makes up a large part of the story. 3. All the male leads are clean. The romance is healthy and slow-burn, and the main story's romance has an open ending. 4. The heroine is the center of the story. There are no side couples. 5. Please don't offer writing advice, mention other novels in my comments, or make baseless comparisons. Those comments will be deleted. 6. I rarely check comments except on the latest chapter.
