Is This Some Kind of Joke? How Did I Become the CEO’s Assistant?

[Two male leads + devoted to each other + transmigration + System + domineering CEO x assistant + ABO + Alpha/Beta + no changes to canon + multiple secondary couples]

Jing Gu was an ordinary college student who liked staying up late to read novels. After another late night, he went out with his classmates and, while crossing the street in a daze, got hit by a massive truck and sent straight into a novel's world.

Jing Gu has always believed in making the best of wherever he ends up. Though he couldn't do much of anything, he calmly accepted a job as an assistant.

Worst case, he gets fired.･֊･

The System tells him that all he has to do is get the male and female leads together to earn rewards.

So, eager to retire early, he throws himself into matchmaking every day.

Although the plot somehow gets completed, with no real mishaps (thanks to his slacking off), why has the male lead's best friend fallen for him!!!!

Maybe, probably, there'll be just a little goofiness. I think. I'm a very serious person in real life, so I'm not sure I can write a goofy story (seriously (o‿∩)).

Oh, right, there might be AA love, OO love, AB, AO, OB, AO... (Maybe. I haven't gotten that far yet, but I have some ideas.)

Both leads are each other's only partners
