I feel the same, even with all this backstory over all these chapters we haven't really seen any reason why Ein would love Diesel and vice versa and we haven't seen much interaction or any affection between the two of them so it's kinda weird idk. I guess because neither of them are actually criminals they are drawn to each other.

Call it soulmates? Even Ein is confused why he feels so protective and affected by Diesel. The author probably has plans for them since they're the most enigmatic of the 2 couples. I think their story would explain more re: werewolves. Since Bexan is a Siberian and Diesel is a Bulgarian husky, their lineage may be somewhat connected. So we get a very interesting way of unfolding their stories. I just hope the author won't settle for anything less because s/he got a good lore going.
I know endgame Ein is crazy for Diesel, but idk the chapter feels kinda off for me, maybe i'll reread this arc again later
Despite that, the author is doing an amazing job at drawing Ein/Diesel, both Ein/Diesel and Yanek/Diesel drawn goddamn hot and sensual, but Ein/Diesel feels so right.
