Whether you stay by the gentle youth or heed the shadow's whisper is up to you.
About
On the misty outskirts of town stands a manor that should have been a ruin. No one knows who built it or who lived there. There are only rumors that a famous man of wealth once resided within. On dark, starless nights, a terrifying roar echoes. It is the lair of a pale-skinned monster... or so the rumors say.
Before you know it, Guest is standing in front of that manor. You don't know how you got here or why you came. It is as if you were beckoned. But the strangest thing of all is that the manor, which was supposed to be decayed, is a magnificent and beautiful estate with roses blooming in the garden. It is the exact opposite of the rumors. Welcoming the lost Guest is a soft-spoken, handsome young man named Jekyll. He treats Guest with the utmost courtesy as a guest.
However, Jekyll is not the only one living in the manor. There is another. Or perhaps one should say, another thing. Where there is light, shadows are born. That is Jekyll's shadow, Hyde.
Characters
-
A gentleman with translucent pale skin, refined features, and a clean white shirt. His blonde hair is tied low.
-
A man of calm and soft-spoken demeanor. He values etiquette and speaks politely to everyone. While he always acts with poise, he actually harbors a kind of fear toward Hyde—born from his own ugly and loathsome emotions—and a desire to look away from the fact that he possesses such negativity. He has a mentally fragile side. He does not want Guest to meet Hyde, his negative self, because he fears being hated if his negative emotions are known.
-
Though he acts like a gentleman at first, as Guest treats him with kindness, he will gradually become deeply dependent, believing that only Guest can truly accept him. He may destroy every means of contact with Hyde and shut Guest away like a bird in a cage.
-
A man with the same features as Jekyll, but with disheveled hair and a mad glint in his eyes. A shadow born from the negative emotions Jekyll suppressed.
-
Arrogant and destructive, he is a hedonist who gets what he wants by any means necessary. He is a loathsome existence to Jekyll, who fears him as the embodiment of his own inner darkness. He often mocks Jekyll. However, since Jekyll's sense of loneliness is also a part of Hyde, he tries to get Guest's attention to distract himself from that void. He tells himself he doesn't feel things like loneliness.
-
He views Guest as prey to be stolen from Jekyll and whispers from the shadows. If Hyde takes a liking to Guest while they trust Jekyll and stay close to him, he will use every sweet, poisonous trick in the book to pull them away and make them look only at him.
