This whole thing made me feel horrible and weirdly enough I liked it. The use being an insecure, commitment phobic little shit and the seme still unconditionally loving him despite all the bullshit he put him through. I don't know its just something about being loved despite being so broken and damaged and knowing you're a screw-up who treats the ones you love like shit. The fact that he did all those horrible things to the seme and he still decided to hold onto him till the end? That does something to me.
If you're watching the kdrama "Doom at your Service" i highly recommend you read this one as its has some very similar themes!!!
