I have seen princess peach being really supportive about the bowuigi relationship or princess peach being really against the relationship
I’ve seen Princess peach, be heartbroken and field, betrayed by Bowser and Luigi getting into a relationship and I’ve seen Princess peach be severely relieved
Do you know what I haven’t seen Princess peach being as worried as Mario like she loves Luigi and wants him to be happy but she’s not sure if Bowser is the one who can give him that happiness
Just imagine her and Mario sitting on the couch in the brothers cottage waiting for weegee to come home from his date. she’s in overalls just in case if he doesn’t come home so that way both her and Mario can very quickly go and rescue Luigi 
When Luigi finally does come back both her and Mario tackle him, asking him a bunch of questions while simultaneously checking if he’s ok
They love lu and will fight anyone who dares to hurt him emotionally or physically that person will have a funeral
 It’s a racing competition, and everyone has their teammates
Bowser has King boo
Mario and Luigi (obviously)
And surprisingly donkey, Kong and peach
(plus any other pairs you can come up with)
So far in the race, everything was smooth sailing, except for the fact that Mario and Luigi’s kart have been making funky noises
They would’ve done something if it wasn’t for the fact that it only started making funky noises about halfway through the races and getting off of your cart in the middle of a race where everyone is going over 100 mph isn’t exactly the smartest idea
Unlikely for them, they didn’t have much of a choice as their cart quite literally fell apart on them as a certain other mustached pair pass by them laughing hysterically at them (Wario and Waluigi)
Luckily, for them, their friend/partner (all depends on whether you ship it or not) saw the whole thing
Bowser and king boo drive over to the brothers at the same time as peach and DK do
In a somewhat sort of silent agreement between the pair that still have working cars, they scoop up their respective Brother and start to drive off
Luigi squeaking in surprise from suddenly being picked up by Bowser
 And Mario letting out his own noise and surprise, as DK grabbed on to him
Mario and Luigi both find out that neither of their new team mates plan on winning the race and instead plan on making sure that Wario and Waluigi don’t win 
Today I learned that we were gonna maybe get Walupeach but she was scrapped bc she "would be just like Doronjo" so I had to do a Doronjo-esque take on Walupeach
