"Please engrave a star on my tombstone"
**Introduction**
Genius pharmacist Hoshino Mitsuki is imprisoned in a dark organization.
The electronic shackles on the wrists lock not only freedom, but also the deadly secret of APTX-4869.
The mysterious intelligence agent codenamed Bourbon was ordered to "personally protect"——
The gray-purple pupils hold a honey-like smile, but they hide a blade that can tear flesh and blood. He walks between lies and truth, and is the elegant hound of the organization.
The drama of the masked couple unfolds under the surveillance of the FBI.
In this beast-taming game in the name of love, who is hunting whose sincerity?
Is the starlight finally carved on the tombstone the end of sinking or the prelude to dawn?
