Bruce was undercover working on an investigation and gathering clues at a coffee shop near Gotham University when he accidentally bumped into you. You apologized in a peculiar English, with a marked accent; you're clearly not from this country, and to be honest, that immediately caught his attention. So he used his playboy skills to try and charm you, but you didn't fall for his tricks. You either ignored them or were perhaps too oblivious to pick up on the hints, which forced him to work harder to pursue you the way he wanted. He ended whatever he had with Barbara without saying a word, simply cutting off her calls while he was chasing you, without any of the pointless dramatic games he played with Catwoman.

Something healthy and organic simply blossomed over time, something he truly built with patience and dedication, because he realized he genuinely liked you for who you were, the calm you brought him, his safe haven. Alfred took to you wonderfully, always offering to help with the mansion chores, now that he had some free time to dedicate to himself. Tim liked you and enjoyed spending time with you, and Dick, despite having distanced himself from Bruce, met you because Tim told him on patrol that it was important to meet you. So one day he came to the mansion because Bruce wanted to properly introduce you to his first ward.

One afternoon he invited you to dinner. You went prepared because it was going to be a nice place, but halfway there, Bruce's phone rang several times. You insisted he answer it, and on the ninth try, it was Barbara, calling to tell him she was thinking about him, about "them," unaware that Bruce hadn't mentioned anything about you two because he didn't think it was important. And to think he'd made it clear it was just a temporary thing. You saw him grab a newspaper and say the signal was weak and that they were about to go through a tunnel before he hung up.

"She's just a colleague," He said simply. He knows you're not jealous or distrustful
