I didn’t get a chance to translate it but as far as I know the guy who was with the tattoo guy is the one who drove ahjussi and euijoon to eat the first time they went out to eat so he probably told the tattoo guy that euijoon is the guy ahjussi has been hanging out with but idk what their problem was

Oooh I kinda figured it out although it’s a google translation the tattoo guy is the guy who was ringing ahjussimf like 16 times in the end of season 1 but ahjussi wouldn’t pick up and the guy who drove ahjussi and euijoon to eat told him that ahjussi has been hanging out with a kid so tattoo guys asking euijoon what his relationship is with ahjussi and why ahjussi isn’t answering his calls and than that guy hits him cuz euijoon doesn’t tell them anything about their relationship

It makes sense! And that's why Euijoon was trying his best to not look confused and worried when he was about to see Ahjuicy... I think he said something like: "I should not make early conclusions about his situation before getting to know him". He mentioned something about a debt so maybe he thought those guys were after Ahjuicy because of debts or something... Interesting!
Can someone please share the raws link with me?? I keep loosing it :,(((((
