I see a lot of people saying Jin deserves better. But it's not as if Jin is the epitome of perfect partner. It is shown how he knows a lot about Kazuomi yet Kazuomi knows nothing about him, and not for the lack of asking. Both have their shortcomings that somehow makes them fit together. To be honest I would have either killed someone like Jin, or at least changed the locks. Kazuomi may not be forthcoming about his feelings, but he does show he cares.
