Maybe the ML got held back? So technically older? But unless it's that, yeah a bit of a plot hole
the author already gave us a clue in ch 2 that they went to the same school. As for why the boss calls MC “kid,” it might just be a nickname for rookies, but I’m not sure either.
They same age …both 25
Yeah but I thought ml might be his senior but no they be same age . Sometimes no many a times yaoi makes absolutely zero sense but what can I do iam obsessed with yaoi so I shut my brain n just reads
I don’t think it’s a plot hole. For me it looked he trying conceal who he really is
Actually teens the same age call each other kid quite often especially between boys. It may also be because ml just views himself as more mature/experienced. Plus that he’s also the boss.
He ML calls the MC kid . Treats him like kid n suddenly flask back- they were class mate they are the same age!! It so confusing. It’s like the author din think of the plot before starting the story. It stared like the ml was somewhat older guy who is protective of the younger mc. did the Mc had some kind of accident he got amnesia? If not how can someone just not recognize your frIend from highscgool. And how is they be going whole night right after getting discharged from the hospital. ML got a freaking stab injury with so sign of any wound whatsoever
