No but Mamoru and Minako as buddies.
They would be the perfect for foil for each other… straight man Mamoru, ridiculous, sometimes over the top Minako.
They’re both used to working on their own without a team, so they understand each other well and have developed a bit of a loner streak at times. So when one of them just needs to get away sometimes, the other totally covers for them.
Mamoru asks Minako for advice when it comes to Usagi, most of her ideas are good… others not so much, but he appreciates it all the same. AND SOMETIMES they come up with completely ridiculous over the top romantic gestures that require doves, a rain of rose petals, and glowing hearts.
They both take their romcoms very seriously and debate plots all the time. Meanwhile Usagi just pouts at them while they dissect a movie because ‘GOSH CAN’T YOU JUST ENJOY IT FOR WHAT IT IS?’
'No, Usagi! This is serious!' they cry in unison.
They sometimes go running together, because they both like to keep in shape… Makoto often joins them too.
JUST MAMORU AND SENSHI FRIENDSHIP! (ﾉ◕ヮ◕)ﾉ*:・ﾟ✧
And shopping trips. Shopping trips! You KNOW Minako wants to dress Mamoru and he wants to dress her and they are both brand snobs while both having really weird taste so they always enable each other to buy really over-the-top bizarre designer shit that every other one of their friends would try to talk them out of.
