Sara Fujiharu, the cutest girl in the school, is also known as the 'Seatmate Bully'. Every few weeks, the class seating changes and every time, Fujiharu-san gets a new target. What's her goal? To make the boy sitting next to her fall in love, and once she does, she destroys their heart, crushing their love.

Why does she do this? I still don't know.

It's March 23rd, the day of the seating change. So far, ten boys have fallen for her traps, her playful attitude, and her innocent face. Not a single boy so far has managed to brush off her attacks-and every single time; their weak hearts have been crushed.

Now it's my turn.

However, my heart is not so easily played with.

But his Awakening failed, leaving him powerless and humiliated—a target for cruelty.Locked away and tormented by those he trusted, his suffering revealed the truth of his origin: he wasn’t just human.Unleashing powers that defy the laws of the world, such as his All-Seeing eyes—capable of negating time, absorbing skills used against him and granting him 360° vision.Seiya rises from the shadows, no longer a punching bag but a force that terrifies demons, monsters, and humans alike.Hero or villain? It doesn’t matter. He’s done obeying, done breaking for anyone.Now, they beg for mercy from the god they tried to crush.
