Two Car stuff
This sounds to me like it was originally intended as a yuri(-ish) sports anime but got given to staff that wasn't interested in that. I remember a while back there was that Buddy Complex mecha show that had something similar happen
Its by the ange vierge staff, so its kinda weird it has faceless males.
Thankfully, the subtext is really strong by atleast 4 couples(ojou team, S&M reversal team, announcers and team 'married'). 2 couples still have not had an episode, so we'll see.
No idea why they are doing both het and yuri subtext pairings, makes no sense.
