@Dooomi ch. 83 is officially out and the complicated circumstances regarding Russell is because—
Spoiler!
They found out Russel is compatible or is a match with someone in their facility. Our main couple initially thought it is Kahim, but it's actually Brian. It's an esper x esper ship, y'all! Brian is like a masoch!st and Russell has a violent personality (it's a match made in heaven lol) I'm kinda disappointed because he wasn't matched with Kahim but I'm also happy with this ship because I already thought about this possibility earlier and I was even looking for esper×esper or guide×guide couples in guideverse. But Kahim is in the training room with them 'cause he was training Russell and I'm telling you there's still sexual tension between them. So, maybe a poly or a throuple between Kahim × Russell × Brian? Pleaseeeeee. even Konrad thinks it makes sense for Kahim to acquire Russell's power (flame/explosion) to incorporate into his wind power (even though K is still salty that he almost died because of Russell lol)
