Ok so question, since the beginning was it actually alek that hyun slept with in the begin...

both

i- uhh can you explain please if you mind doing so?

So after the party from the first chapter, Hyun and Alek were both pretty drunk and woke up in the next morning, sleeping next to each other naked. So originally, we thought they had sex but it turns out to be a threesome between Ivan, Hyun and Alek.
It appears that after the party, Hyun met Alek and somehow they had sex. Ivan only wanted to make Alek feel miserable (or to just piss him off), so he had sex with Hyun, but in the middle of it, Alek came in, saw them doing it and lost it because of the pheromones (plus he was quite drunk) and so he just jumped right in lol ╮(￣▽￣)╭
In the end, it was Alek who marked Hyun and that's the reason why his condition is getting out of control lately, as we've seen in recent chapters.
Also chapter 89's just been uploaded you''ll be clearer once you've seen it.

OMG I got Ivan and Alek names messed up loll
OK just forget it you'll get it once you see chapter 89 :'>

thank you so much!!
