One thing that Karasu was very well aware about himself but wouldn't say out loud to anyone, was that he was mediocre, ordinary, vulnerable, like any other person.

He'd been putting on a bravado all his life, acting like he was confident while internally analyzing and assessing people, especially ones who he deemed mediocre, just to poke at their weaknesses and make himself feel better. So it wasn't a surprise that even in a relationship, he couldn't see how much of an amazing boyfriend he was. Or maybe he'd just never been in one where he felt like so, and well, the root cause? His best friend–Otoya Eita.

Otoya was an extraordinary striker, in Karasu's opinion. Despite their differences in lifestyle and mindset, the two had one of the best chemistry on field, and Otoya's carefree personality definitely put Karasu at peace because he didn't have to think as much around him. However, the mere presence and flirty nature of his best friend were also the things that led the majority of his past relationships to shambles.

Look, not that Karasu blamed Otoya or anything. Nevertheless, whenever the latter showed up and start blurting out some harmless advances and proposals to his exes (which ranged from hanging out to more explicit things in bed), they always fell for it, not all of them, but a noteworthy number did. Sure, Otoya wasn't after anything but fun, no feelings involved, but still, it didn't stop Karasu's relationships to sour due to either comparison or not-so-subtle pining over his best friend from his so-called ex lovers.

He wasn't even jealous, he could see it coming from miles away, couldn't even be surprised anymore if it happened again, but it left him incredibly worked up and insecure every time, though the blue-eyed athlete would never admit that.

Was it too much to wish for someone who wanted him and only him? He was a gentleman, even if he appeared to be a teasing bastard sometimes, he checked all the boxes alright, so why couldn't they stop looking at his best friend instead? Even his sharp mind couldn't conjure up an answer.

That was why right now, after watching you chatting and getting along a little too well with Otoya for a whole afternoon, Karasu was a little (very) concerned. Please don't get any funny ideas, not this time, not again.

"Ya know, he only wanna get into yer pants, right?" Your boyfriend muttered under his breath, rubbing the back of his neck.

Was that out of character and kind of desperate? Yes, but Karasu was really at his wits end here. "Do ya like him or somethin'?"
