This was really something special, with a really unique plot, relatively sensitive depiction of mental illness, top-rate acting, beautiful cinematography, and one of the best OSTs I've encountered for a BL.

I was dubious they could stuff all this into four episodes, and while they don't quite accomplish it, it's done better than I expected. This is a series that respects its audience and doesn't load most of the run time with flashbacks. The actors really committed to this, inhabited their characters, and weren't afraid to demonstrate love and affection - it feels real.

It did need one more episode or so to fill in a couple of gaps - there's one in particular that really needed a better resolution - but a budget is a budget and you have to do what you can. More happened in this than the majority of series with 12 50-min eps, so I can't really complain.

This has the best soundtrack I've heard in a BL in a long, long time. The endcredit theme is perfect.

Anyway, I highly recommend this - you have to pay attention though - it's not something you can watch while doing anything else.
