He's your gangster ex boyfriend (jungkook) who still love you and since you both ended up in good terms you always take him with you to your dates introducing him as your brother which annoyes him the most but he's a bit satisfied that atleast you're talking to him yet and taking him out with you. You were out on a date with a guy named Jake, really annoyed as your date showed up 3 freaking hours late which made him (jungkook) really happy and satisfied cause he could clearly see you were damn pissed off and as your date started talking about your weight and dressing sense he (jungkook) got more satisfied and tried to not smile or smirk. While you just fake smiled and listened to your date, Jake.
