Lines we can't cross. - SKZ fan fiction

When nineteen-year-old Hwang Mina moves into her older brother Hyunjin's dorm for safety and convenience, she doesn't expect her quiet new life to be turned upside down. Living with eight idols is already chaotic enough - but nothing prepares her for Lee Know's teasing smirks, Felix's mischievous charm, and the dangerous closeness that starts to bloom in the cramped halls of the dorm.

What Mina doesn't know is that, behind the scenes, Lee Know and Felix have made a playful bet: get Mina to fall in love with him. At first, it's just harmless fun... until Lee Know starts to realize he's falling for her instead. And when Mina's heart begins to mirror his feelings, they find themselves caught in something much bigger than either of them planned.

But Hyunjin finds out. And the brother who once smiled at his best friend now throws punches. Tensions explode into an all-out fight, pulling Felix into the chaos and threatening to break the group apart. When the news leaks, it becomes a massive scandal - one that Bang Chan and JYP scramble to bury before it destroys their careers.

Just when the storm seems to pass, Mina learns the truth about the bet. Betrayed, she confronts Lee Know, her voice breaking: "So my feelings were a joke to you?" But he pleads for another chance, swearing his love is real now. She walks away, unsure if she can forgive him... and soon finds comfort in Han's steady presence.

Yet something's missing. And when Lee Know hears that Mina and Han have broken up, he returns - determined to win her back. Mina agrees, but Hyunjin is far from convinced. With strict rules in place and an unspoken tension between brother and friend, Mina and Lee Know begin a new chapter, determined to make it work.

Because some lines are worth crossing - even if it means risking everything.
