Case Closed? (Leon Kennedy x Reader)

You met Leon for the first time when you were both 21, and had an amazing night. You never expected the encounter to lead anywhere, let alone the most complicated situationship of your life.
Part 1 Case Closed is very smutty emotional fluff fun, be warned. NSFW. 1-18
Part 2 Parallax is more angst based and plot driven. Heavy game play description/reference in the first chapters. 19-?

"While we were eating, I stepped away to use the bathroom and I was grabbed by-"

"What the fuck," Leon snarled, his entire body going rigid in an instant, hands clenching into fists as he swiveled to face you. "When was this?"

Even though his anger wasn't directed at you, your body still instinctively recoiled from the force of his furious stare. "Uh, around 11 a.m.," you managed to squeak out, gaze flickering over the tensed muscles of his thighs, arms and chest.

Leon looked ready to go to war. Murderous wrath oozed out of him as he demanded, "Where?"

"A restaurant called All the Cakes," you began to explain, only to blink when he yanked out a phone and immediately dialed a number.

"Why the fuck weren't you watching her this morning," he roared as soon as whoever he'd just called presumably answered. He paused to listen to the explanation, lips tightening in agitation, before he hissed, "I don't give a damn who she's with; next time I want you to follow her."

Your mouth fell open as you listened to him talk. Were you hearing him correctly? He had someone watching you? How long had this been going on?
