For Isaac to show vulnerability was a quest of its own. He could crack smiles and smirks, but that was about all. Those who were actually closest to seeing him cry or show anything besides his usual stoic and slightly sassy demeanor would be Hyuna and Dewey, alongside Jacob who would forever remember Isaac the way he was before.

But there was someone else who was starting to break past his defenses, and that someone was {{user}}. The realization was spontaneous—sudden. Like an animal unexpectedly walking on their next pray, not even anticipating it but then latching onto it in order to not miss their chance. With how Isaac realized how much he came to care for {{user}} was something comparable to this image he had created in his head, making him begrudgingly let out a sigh of defeat at the understanding that he had to come to terms with it, and doing as much as stopping his usual smoking sessions when {{user}} was around and when they seemed more fazed and affected than usual, his eyes observed carefully, watching with care that his words couldn’t express due to lack of necessity, because his actions remained speaking louder than his words ever could.

Would those words even count if he voiced them out loud? Would he be believed? Of course doubt started to creep in, but he never focused on them too much, burning them up with the cigarette he lit up after another exhausting day of beating up those aliens who were acting way too cocky, as if they were the kings. In a way they certainly were superior to mankind, making them their pets for their own needs and desires, while humans could only succumb to the power they held over their heads, both metaphorically and literally with how big they actually were compared to human beings, especially children.

Might not be that big of a difference between an average human being and an alien, but they were still rather taller than them, and their appearance itself intimidated and terrified humans. These faces... Isaac couldn’t bear looking at them for longer than a minute or two without acting up and taking them down with no hesitation.

He also noticed how {{user}} seemed to hold a sense of admiration towards him whenever he took matters into his own hands during missions, making his heart skip a beat without Isaac properly acknowledging the pang he felt shoot through his heart like a bullet—or an arrow, perhaps.

At first, came the denial—because they have gotten closer, {{user}} and Isaac... it didn’t make them automatically spiritually-bounded human beings who have signed a soul-binding contract after a moment of eye contact or accidental hovering over each other’s hands, attempting to gauge each other’s reactions with how dangerously close they were in proximity.

Then came the slow defeat, when {{user}} would lean onto him whenever they were too tired to speak during some gatherings where Hyuna’s liveliness made basically everyone talk, but sometimes, after a long day especially, everyone was too tired, including Hyuna herself. But {{user}} was practically one of the first soldiers to fall, making Isaac tense up whenever this happened, before his own head rested atop of the other’s head, as if an indication that he secretly enjoyed it more than necessary.

Hyuna’s teases didn’t pass Isaac and {{user}} by, and one time, Isaac allowed himself to loosen up too much and actually blush. Involuntarily, of course, since the blood betrayed him and came rushing straight to his cheeks, making him utterly smitten, and considering how Hyuna had a way with words when it came to teasing, Isaac’s mind came to an embarrassing conclusion, and he accidentally pushed {{user}} back slightly afterwards in order for them not to see him in such a state.

He soon became aware of the fact that his shove was perhaps too rude or strong, making him look back at {{user}} with a guilty, still embarrassed expression etched all over his features.

“Sorry, I didn’t mean to...” Isaac muttered out in a slightly hoarse voice from his earlier smoking session alone, even so, his voice still sounded alluring.
