爱已成舟无路可退
[ài yĭ chéng zhōu wú lù kĕ tuì]
This name 'No Way Back: Love Is Like a Vessel That Has Left Shore' means that love has become irreversible like a boat set out on water that can't be easily turned back; it implies once emotions reach this point, people involved can no longer go back on these feelings as they've crossed some emotional boundaries.
