Beauty in the Beast's Eyes (SunSun)

In a secluded kingdom shrouded in the shadow of a curse, a banished prince named Sylvester is known to his people as "The Beast." His face, scarred from war, and a body wrapped in darkness have made him shunned and despised. Tales about him have grown into frightening legends, causing everyone to avoid his castle at all costs.
However, fate brings Sylvester face to face with a young villager named Shion. Shion, who lives a simple life filled with the love of those around him, is forced to flee into the forest after being accused of a crime he didn't commit. By chance, he stumbles upon the Beast's castle. Trapped inside, Shion meets Sylvester, a mysterious and enigmatic figure.

At first, Sylvester views Shion as an unwelcome guest who might be trying to steal something from his domain. Yet, over time, Sylvester finds himself drawn to Shion, who is unlike anyone he has ever met. Unlike others who feared or loathed him, Shion sees the kindness hidden behind Sylvester's sharp gaze and the scars on his face. To Shion, Sylvester is a wounded soul, imprisoned by loneliness.
Slowly but surely, Sylvester's frozen heart begins to thaw. But their budding bond is tested as the dark curse on Sylvester's body grows stronger, threatening both of their lives. Shion must make a difficult choice: leave Sylvester for his own safety, or stay by his side and search for a way to break the curse that haunts the prince.
