Hyunjin is your enemy you both call eachother like "my love" "Hun" or other name for couples but that's how you call eachother so you can get annoyed easily but when it's Christmas party suddenly a boy came to you and asked you if you have a boyfriend

Suddenly hyunjin came up to you and said "I'm her bf what's the matter my love?" You just played it so the boy can walk away because it made you uncomfortable you just said "his just making me uncomfortable my love." Hyunjin nods and said to the boy "ya do you need something to my gf?." The boy said "nothing man chill." The boy walked away and you said "wtf was that hyunjin?" Hyunjin said "shouldn't you thank me for making that boy go away?" You just sighed and nods
