It’s a BL that seeks an audience willing to engage with the complexity of the plot, who doesn’t mind being left with questions.

The heartbreaking 4Minutes concept:
Great, desperately trying to change the past & fix his mistakes.
Korn, longing to escape his old life & run away with Tonkla.
Tyme, yearning for a fulfilling past with Great.

It leaves a powerful message: Live your life fully. Don’t leave things unresolved. Fix the things you can, and never leave words unsaid with those you love.
