The romantic nature is "calibrated" and love no longer overflows. Focused under the camera, her light no longer diffracts and becomes her Bessel light... When a female college student bravely breaks into the tiger's den, what comes to her is the passionate love of a prodigal son, or is it jealousy of happiness? (The title of the book is borrowed from Bessel beam principle)
Concept: Love is the only light that does not obey the laws of diffraction.
