The plot build up is good, the representation of the trauma is well portrayed. Honestly this hit close to me, i've suffered before, and due to guilt i bound myself to self harm. So i love the seme here, how he comfort the uke, the constant reassurance that the uke is doing good, and he is well needed and cherish. Yep its dark but this is beautiful. Even the 2nd story is ok.
