3.5 stars, rounded down because of how irritated I am.
The story about Carol was really interesting, as was learning about why Dee became a cop...
...but Ryo acting like he is doing Dee some massive favour by giving him attention, or access to his body, makes me want to hit my head against a wall repeatedly.
At this point, Dee should meet up with Diana and just hook up with her. It would never work out long-term, but they would both have fun until they agreed it wasn't going anywhere and moved on. At this point, Dee repeatedly sets himself up to get hurt (and does) as if this time Ryo may actually wake up one day and love him.
Honestly, the similarities between Dee and JJ are just sad, in both cases. The fact that Ryo probably does love Dee in return makes it worse, because he has absolutely zero guilt for how he treats him. Massive "main character" syndrome with that one.
