That Butler, Isekaid (Modern!Reader Insert)

That Butler; Claim

_________ nods, smile still on their face as is their blush. Before walking out and closing the door of the library behind them. Leaving him alone with his thoughts

Anger, pain, disappointment, longing, and anguish overcome him like a tidal wave. Enveloping him, to the point that he can feel his heart being torn apart

_________ loves someone, and now he is left with the knowledge that they'll never be his. Their heart already is with someone else, and he can't help but feel a pang of jealousy. Who the hell is it? Who dares take what should be his?!

He slams a fist down onto the table, anger and jealousy swirling in him. He can't just accept this. Who is it?! Who had the opportunity to sway their heart? Why not him? What does that person have that he doesn't? It's not fair...

Ciel's anger and jealousy consume him, his emotions swirling like a tempest within his chest. He can't accept the fact that someone else has captured _________'s heart, that they belong to another. It feels unjust, unfair, and it stokes the flames of his frustration.

He paces back and forth in the library, his mind racing with questions and doubts. Who is this person that has taken _________'s heart? What do they have that he doesn't? What did he do wrong? The thoughts gnaw at him, fueling his anger and self-doubt.

Ciel's anger simmers beneath his composed exterior, his heart throbbing with a mix of jealousy and frustration. He paces back and forth in his study, his mind consumed by thoughts of who could possibly have won __________'s heart. The burning question gnaws at him, taunting him with its unanswered mystery.

He clenches his fists, his nails digging into the palm of his hands as he tries to quell the surge of emotions within him. He can't bear the thought of ________ loving someone else, of another person having what he desires so desperately. It's not fair, it's not right. He wants to scream, to break something, to unleash the fury that simmers beneath his composed exterior. The pain of unrequited love cuts deep, but it is the sting of jealousy that fuels the fire within him.

Unable to contain his frustration any longer, he slams his hand against the bookshelf, a mix of anger and determination etched across his face. He refuses to accept defeat, to let another claim what he desires so fiercely.

"Damn it! Who is it? Who has managed to capture their heart?!" he seethes, his voice filled with a mix of anger and desperation. "I won't let them have them! I won't let them take what should rightfully be mine!"

His mind races, thoughts of revenge and reclaiming what is his consuming his every thought. He won't allow himself to be defeated, to be left with nothing but a hollow ache in his chest. He won't allow it! He won't hand them over to anyone, no one!!

Ciel's emotions spiral out of control as anger and jealousy consume him, his thoughts filled with a burning desire to know who ________ loves. He paces back and forth in the library, his mind racing, unable to find solace in his fractured heart. He slams his fist onto the wall this time, frustration coursing through him like a tempestuous storm. It's not fair, he thinks bitterly, the bitter taste of envy lingering on his tongue. Why does someone else have ________'s heart when he so desperately craves their affection? What does this person have that he doesn't?

His mind races with countless possibilities, trying to pinpoint the person who has invaded his thoughts and claimed _________'s affections. He feels consumed by a mixture of anger, jealousy, and longing, a toxic cocktail that threatens to reshape his entire world.

He tries to calm himself, his fingers trembling as he clenches his fist in frustration. The realization that someone else has captured _________'s heart gnaws at him, fuels the fire of his jealousy. He can't understand why it couldn't have been him, why fate had dealt such a cruel hand. Sebastian, always watching and observing, appears by his side, his voice calm and composed as he addresses his young master. "Master, I understand that this news has upset you. But might I remind you that __________ is still not of this time? None of us have insight as to when they'll leave back to their own home. Seeking them will not guarantee that they'll stay."

Ciel glares at Sebastian, a mixture of anger and resentment marring his normally calm expression. Yet, deep down, he knows his butler's words hold a measure of truth. He grits his teeth, trying to find his footing amidst the whirlwind of emotions that threaten to consume him.

Ciel's anger and frustration begin to subside slightly as Sebastian's words sink in. He takes a deep breath, his mind slowly clearing as he tries to regain his composure. He knows that Sebastian is right, that seeking _________ out may not guarantee that they will stay. But the ache in his heart still lingers, the longing for _________'s affections still burning within him.

"You're right, Sebastian," Ciel concedes, his voice a mix of resignation and determination. "But I can't just sit back and do nothing. I can't let someone else have what I desire so fervently. I must find a way to make _________ see that I am the one who truly deserves their heart."

He straightens his posture, the fire of determination reigniting in his eyes. He won't let his jealousy and longing consume him. He will find a way to win _________'s affections, to prove that he is the one who can make them truly happy.

"It would be futile to pursue _________, and if their heart already belongs to another. And even if I were to win them over, there is no guarantee of how long they will stay in our time." His words are laced with a sense of defeat, his eyes downcast as he struggles to come to terms with the reality of their situation.

He takes a few steps back, his pacing coming to a halt as he stands before his loyal butler. The anger and jealousy that had consumed him moments ago now give way to a sense of sorrow and acceptance. _________'s heart belongs to another, and he must find a way to come to terms with that painful truth.

A heavy sigh escapes his lips as he runs a hand through his disheveled hair, his gaze fixed somewhere beyond Sebastian. The realization sinks in, the bitter taste of unrequited love lingering on his tongue.

"But I still desire them. _________burns my soul, it would be agonizing without them. A feeling most likely worse than any death..."

Sebastian, ever the calming presence, kneels before his master. "If you wish it so, simply order it. And you shall have what you desire"

Ciel's heart clenches at Sebastian's words, the temptation to order him to make _________ love him overwhelming. But deep down, he knows that such a command would be meaningless, that it wouldn't truly win _________'s heart. Love cannot be forced or manufactured, and he understands that now.

With a heavy sigh, Ciel shakes his head, his voice filled with resignation. "No, Sebastian. Love cannot be commanded. It must be freely given. I cannot force _________ to love me, even if I desire it with every fiber of my being."

"And besides. I have more important matters to attend to. My revenge... will be my focus."

But Ciel's temper flares under his calmed façade, his thoughts becoming dark and obsessive. He can't let this go, he can't accept that someone else has become the sole recipient of _________'s love. He is willing to go to great lengths to protect what he believes should rightfully belong to him.
