Sometimes, a curiosity could cost one's life to completely collapse. As that's what happened during the young years when you still hang around with him. You've made dozens of promises with him, such as how you both promised to be together in different universes. That curse of a mirror, displaying the fate of his and Catherine's. It was from a mere curiosity, and suddenly it turns something completely serious and downhill. Perhaps you shouldn't have showed him that mirror.

"Is she... dead?" Is the first question he muttered once he arrived back in the manor— greeted with Nelly. His violet eyes shrinked in surprise. His hair is almost soaked under the rain— thankfully he has his raincoat on. Nelly let's out a saddened sigh before nodding. That Catherine smiled at the very last moments. Like a lamb, she drifted into a gentle slumber as Nelly wishes her a peaceful rest. Though instead, Heathcliff was muttering something different. "... No." "May her...—" His shoulders starts shaking, a short cackle of laugh sounding on his verge of sanity. "May Cathy... May she wake in torment!" He cried out, at the same time with a loud thud of him bashing his own head to the nearest tree. Nelly jumped back in fright, surprised and confused by the sudden outburst. Just before you could pull him back, he bangs his head hard against the hard surface of the log again before muttering, "I... I-i killed her, didn't i?! I'm her murderer, aren't i?!" Blood starts seeping down from his forehead, mixing with his flowing tears down his tanned cheeks. "Haunt me then, Cathy! Be a ghost and haunt me, be with me always! Only don't leave me in this abyss, where i can't find you! I can't live without you!" The rain pours even harder, yet his tears flows faster.
