A lot of it is done by b-team studios.
Unless it's a big budget movie like Saezuru or Etranger most of the time they aren't handled as well as normie series.
Even tho bl has experienced a massive boom in popularity, it still isn't the norm as far as jp anime otaku are concerned. Thus, they get the leftover studios while everything else gets Ufotable and etc.
Can't help it but I think it would be great if this manga gets anime adaptation (well... if only japanese BL anime studios improve their way of doing animations)
