Summary
Isshiki Totomaru just wanted a normal job, with normal wages and a normal life. When he's hired by Tokyo's leading confectionery industry, he couldn't believe it. No matter what, he'd make the best out of this opportunity! Or so he thought.
Enter Kamonohashi Ron, the eccentric and mysterious CEO. For some reason, he's taken an interest in Toto (if you could call it that) and is hellbent on irritating the life out of him.
Totomaru should've just been a deliveryboy. Atleast that didn't include "mentally exhausting" as part of its job package.

Summary
“So, your dad’s a detective, huh?”
At that, Knight’s expression shifted. His eyes lit up, a rare spark of excitement replacing his usual stoic demeanour.
“Yes,” he said with pride, his voice steady but tinged with a gleam of admiration. “He’s the greatest detective in the world! Once I grow up, I’ll beat him and become the greatest.”
Toto blinked in surprise at the sudden passion in Knight’s voice. He smiled warmly, leaning in slightly. “That’s a big goal. You must really look up to him.”
Knight straightened, his serious face back in place, but the glow in his eyes remained. “I do,” he said simply. “But he kind of has a weird habit sometimes”

The Case of a Knight (Bran, Jr.) in Love by JadeGM

Summary
Amidst all the chaos with the M Family's increasingly direct targeting of World Detective Association branch leaders and the frantic search for Alice Moriarty, the identity of Knight Bran Jr.'s first girlfriend is far too shallow a mystery for BLUE's other surviving top students to concern themselves with - let alone anyone else at that vaunted institution. However, given that they're all world-class detectives, they can't avoid picking up a few things about her in the course of their daily lives.
This leads to outside observers making brilliant deductions about Knight's girlfriend that completely miss the important part... and a simple conclusion that only the two of them could reach.
