I know that he used to drug him ? who doesn’t that’s why he’s hated lmao. And partly why he got a flashback but like I said it was because Mathew was calling out his full name “cheong-woo” instead of just Jin why else would Jin be saying “don’t call me that” then later saying “it reminds me of (flashback being bradon)”
Btw here’s the translation and how it goes
Mathew :”Jin-cheong woo”
Jin :don’t call me that
Mathew:”why not ?its your name.” “You don’t like when I call you by your name.?”
And then Jin is mind says - “that name is..”
which is when the “flashback” of Brandon on top of jin shows where Brandon asks Jin “cheong-Woo are you okay?” To where he responds “yes Hyung”
THE NAME BEING THE ONE THAT MATHEW WAS CALLING JIN BUT JIN DOESNT LIKE IT BECAUSE IT REMINDS HIM OF BRANDONNNN
YALL THE REASON JIN SAW A FLASHBACK OF BRANDON IS NOT BECAUSE HE MISSES HIM OR WANTS TO BE FUCKEF MY HIM. It’s because Mathew was calling jin by his full name which is something Brandon used to do which is why he had a flashback. That’s why Jin was telling Mathew “don’t call me that”
