" How could you do this to us ? I thought...... I thought we are family. Or was that also a lie . " Jungkook said while sobbing and begging on his knees .

He couldn't believe that the person he trusted the most can betray him this hard. But if it was just a betrayal, he would have taken it with smile, just because it's his Taehyung on the other side.
But what he did was beyond any betrayal, at this point he will anything so he had never meeted Taehyung.

His Small little tae tae.

Jungkook and RM lost their parents at a young age and had to figure out life on their own. Despite their struggles, they were never alone, thanks to Taehyung-RM's mute but bubbly best friend from a wealthy family.
Taehyung always visited them, never caring about their lack of money, and became a constant part of their lives.

But things started changing as they got older. Jungkook, who always saw Taehyung as a little brother, began to feel something different after a certain event. His emotions started growing, but Jungkook tried to push them down, afraid of what it meant.

Can he stop his feelings from growing, or will his heart take him somewhere he isn't ready to go?
will taehyung reciprocate his feeling ?
