It's a oneshot made by the mangaka who made I Like You Who Can Have Sex Anyone. (Which I really like.). I added this entry since the Google Translated description sounds a bit interesting, the cover was intriguing, and I hoped someone would scanlate another one of Takeda Super's works.
The oneshot itself is nowhere near as graphic as the cover makes it out to be by the way. The cover is honestly quite misleading.
Immaculate. If the foundation of a person's redemption is that cheap, it deserves to engulfed in the flames of vengeance. It's kindness enough that the girl who accompanied him for that "apology" was spared by the MC.
