Also, when they have sex in chapter 36 and they are in really intimate moment, Ein do nothing without Diesel request, he just wait to Diesel said, that "put it in", like he want to be sure, that Diesel wants this, not only him. ( http://www.mangago.zone/read-manga/wolf_in_the_house/nmt/c036/4/)
Their relation seems to be very deep. I love Ein more and more with every chapter, when new details are showing and we can understand better Ein behaviors. It s so good, that Diesel has him.

I don t feaar, that Diesel leave Ein now, but I afraid, that Ein want to leave Diesel for his safety, specially if things turn in something yet more dangerous and incalculable.
Ein wonders in chapter42, that he s doing the right thing, staying with Diesel ( http://www.mangago.zone/read-manga/wolf_in_the_house/nmt/c042/11/).
Diesel would be opposite, he probably only just starts to realize, how important Ein is for him and he woudn t give up on Ein no metter what. Even Minsuk said something like, that ( http://www.mangago.zone/read-manga/wolf_in_the_house/nmt/c041/2/). Also i remember last scene from season 1, when Diesel said, that he would go crazy if someone he loved want to leave him, so Diesel for sure woudn t let Ein do this.

Me too. I was sure, that Ein really loves Diesel since chapter 16, when Minsuk was watching how Ein was sad, when sunset coming and Diesel turned into wolf. On the beginning Diesel seems to me more attached to Ein, than loves him. Little like dog is attached to his owner. Its easy to understand after so many bad experiences in Diesel life. After torturing and was raping for some period, he totally fall in love in person who used and betrayed him. Diesel knew about this, but he still staying with him, like dog who can t leave his owner no meter what. In chapter 20 after this all experiences Ein told to Diesel, that he can t trust people(including himself) for his own sake, cause they betray him. Diesel was just wondering, that he s able to love, not only follow his master/human like dog. So he was distance to his feelings, even when they look like love. Diesel said in chapter 19 to Bexan, that his love for Ein grows with each passing day ( http://www.mangago.zone/read-manga/wolf_in_ the_house/nmt/c019/39/), but he still seems to not believe, that he able to feel love, Diesel doesnt trust in his own feelngs and he s critical towards them. So yeah, i think, that why Diesel is so aloof.
I really like Ein behavior, when Diesel ask him, that what is between them is love ( http://www.mangago.zone/read-manga/wolf_in_the_house/nmt/c031/17/). Ein is in love and he know, that, yet he doesn t give answer for Diesel, he just give Diesel space to let him find answer by himself. Ein doesn t force Diesel to see their relationship like he does this. I think, that Ein gives Diesel in that way possibility to leave and make his own decisions in case, when Diesel realizes, that what he feels is not love. I also think, that Ein could easy force Diesel to accept his point of view, cause Diesel is still half-wolf and his canis instinct is strong, but he doesn t want to this and let Diesel freedom in this way.
Ein is beautiful man. (▰˘◡˘▰)
Poor Diesel...I literally felt disgusted when I seen the many needle marks in his arm and the fact that he was raped made me even more infuriated.
This explains why Ein never puts a leash/collar around Diesel's neck when he's a wolf...he doesn't want him to feel tied up or restrained
