Shitasaki kara Koi

In this world, there are two special categories of people known as "forks" and "cakes." Forks—the predators, normal humans who lack a sense of taste. Cakes—the prey, the one thing forks find irresistibly delicious, often luring them to commit heinous crimes.

The explosion of sweetness has him falling head over heels for the flavor...and for the boy himself!
