You have always liked jungkook since high school days but to him you were just his best friend and neither you ever gave him any hints or confessed your love

he's been urging for a romantic partner who can understand him, love and support him all this time blinded by the fact you've been doing this exact same thing for him since forever, you were here the whole time the one he's been looking for but he just can't see you

he appreciated the efforts but as a best friend never as a lover and eventually found a girlfriend with whom he never has been compatible

"I don't know..she always just doubts everything.." jungkook ranted to you about his gf while your thoughts were just going "what you've been looking for has been here the whole time"
