Our first meeting was good, but
As time goes on, relationships become entangled and
It seems we were destined never to meet.

- Kim Tae-hyung (23 years old)
The female lead's boyfriend, in his second year of dating
Jimin and Yeoju are childhood friends of seven years.
I went astray in high school and was part of a gang of bullies.

.
“Don’t cross the line. His girlfriend is me, not you.”

- Park Jimin (23 years old)
He has been friends with Taehyung for 7 years and with the female lead for 11 years, a childhood friend.
Unlike Taehyung, he lived a very diligent life during high school and never missed being ranked first in the entire school.
The person whose psychology is the most unfathomable(?)
.
.
.
Lines aren't meant to be crossed, they're meant to be kept.

- Seon Yeo-ju (23)
I'm dating Taehyung, but...
I've liked it since middle school.
Unlike Taehyung and Jimin, he is still immature.
.
.
.
You were the one who drew the line called "friend" first.
.
.
But what if I cross that line?
Our relationship has gone completely awry
Where did things go wrong for us...
