I agree with others that I don't think they should get together in the end, at least not for a long time. The love they have should stay platonic until they're both in healthier situations, especially him. Also getting into a relationship would probably make her life worse until all the unsavory characters are gone.
On another note, here's a few songs that I felt fit the mood of this manhwa. Virtual angel- artms. Crooked the road - mon rovîa. I got u - twice. Feel special - twice. The longest time - carley rae jepsen
