@Mithian I totally agree with you but Ian has always lived a life where he couldn't ask for more whether when he was living with that old shi*** hag or with Ray. So when he finally got a place where he could draw his passion as well as take affection from somebody he made his mindset to never ask more just as how raynold wanted as he stated in one previous chapter" you are not like them, right?" Stating That Ian is not like the ones who wants more than affection. I guess that made him not want anything from Ray but affection. He couldn't leave Ray  or hate him because he was Ian savior and one who gave him a name in the society.
Ray on other hand was always the one who seeked revenge. He had such mindset since he was a child so he cannot give up on revenge just like that just because he found someone he loves. He did everything from sleeping with people to being with shitiest people to doing every bad stuff just to get wher he was so ofcourse he couldnt give up fighting for revenge eventhough his heart asked for not doing so.
They both are in state of dilemma which is the result of their past life that they lived. I just feel it is as real as it gonna get. It's not like everybody is strong enough to let go of their past and their motives and their love. I hope they find their peace.
