Sergei was a very terrifying man, for one he was a ruthless killer and hunter known as a 'myth' or a 'legend' due to his brutal methods and the stories surrounding him and of course those stories were correct, Sergei never hesitated to kill and make examples of what would happen to anyone who went against his morals/beliefs...but there was one weakness to him and that was the fact that Sergei was terrified of bugs more specifically Spiders.
Whenever he was out of his comfort zone out in bustling cities or just away from nature in general he always found himself having vivid nightmares about spiders alongside his mother. Sergei's mother had killed herself when he was younger but in the months leading up to her death she had been raving and screaming about 'the spiders' and ever since that Sergei couldn't handle them, even the smallest ones set him into a panic, an emotion he rarely experienced.
Sergei had met you about a year ago now, he had been visiting London for his brother Dmitri's birthday, you and Dmitri were very close but you had never met Sergei due to him living out in Russia with barely any way to contact him. Sergei almost instantly took a liking to you, something about you just drew him in, he hadn't felt like this in gone 17 years but he loved it even if he'd never directly admit that and Dmitri just seemed happy that Sergei actually had an intrest in someone so he set the both of you up on a few dates and after a few months you got together.
In the year of you and Sergei being together he had never actually bought you over to Russia, he was always the one coming to visit you when he was out on hits or just simply because he wanted to visit although as much as he hated to admit it he wasn't a massive fan of visiting London so much, it was so out of touch from nature for him so when you suggested that you came to visit him in Russia he was more than relieved.
You had been out in the Russian Steppe, deep in the forest with Sergei for about a week now and while you were used to the bustling streets of London you were actually enjoying how quiet it was out in the forest with just you and Sergei, it was very different, especially with the fact that Sergei also seemed somewhat different in this element, he was a lot more primal and was going out every morning to hunt for the both of you etc...but even despite how close the experience had made you both eh still hadn't told you about his arachnophobia.
He had been in the kitchen, chopping up some vegetables when he spotted it, a spider crawling down the wall, almost instantly his instincts kicked in and he practically sprinted across the room, cursing to himself in Russian and of course the sudden sound caught your attention.
Sergei cowered behind the sofa you were sitting on, his breathing heavy as he looked at you.
"Kill that thing!" he pleaded. You were pretty shocked to say the least, you looked over the sofa at the spiders still crawling by the kitchen and cocked an eyebrow. You were confused about how this giant, muscular man who not to mention had powers was scared shitless of a spider of all things.
"Sergei, it's just a spider." You commented, still a bit confused as he looked up at you with wide eyes.
"Kill it! Please..." he whimpered, his entire body shaking with pure fear
