I mean, the inicial plot of, as the title says, made it sound, at least in my head, that this will be like Impossible, and then we need to resort to team work and some clever and unique situation to try to reach to Yuzu in a way she gets the hints. But with the "lol she really meant back then that we HAVE to stay as friends, so let's do that if that is what Minami wants" (cheap) twist, now it's like "easy mission for Minami, but we need Yuzu to stop thinking like that and just go confess/dont ingore the hint", because if Minami is the one confessing, then good, but is less impactful as a resolution of the plot IMO.
At this point, if I (hopefully We) want this development to the confession to be more impactful and interesting, the author needs something a bit more dark and maybe depressing (since we got that "cheap/overused" dark twist about Yuzu's past) event. My idea is (It doesnt has to be exact, Im kind of oversimplyfing here): Minami goes on another date with Yuzu, but this one is a more thoughtful one so she is able to have more coraguoe to confess to Yuzu, Minami work hard for this special date, and she gets to confess ((maybe as best as she could)) but Yuzu forces her twisted "reality/TRAUMA" into the actions MInami takes to reach her heart, and again dismisses the signal of romance and plays dumb. MInami then gets fed-up and starts to cry, showing how tired is she from failing numeous times ((I feel like this fits well with her personality, since she also got emotional and twisted things a couple of times)), and Yuzu, still in her world, worries a lot for her from the sudden burst of tears of Minami. Minami runs away, Yuzu goes after her but failed to keep up with her and looses her.
Yuzu, confused and tired, wonders why this happened on the spot, and suddenly Kamiya confronts Yuzu, asking her: what is worng with you? You broke her heart by doing your thing again! explain yourself!
Yuzu goes again about how she heard from Minami when kids, " heard very loud and clear(cause trauma)", "Let's be BFF" from Minami to her. And Kamiya rages on Yuzu: And that's it?! you are constanlty living in the past, of course you will fear the posibility of ruinning the only most precious thing you have from then. BUT stop it! kids can be dumb, so your destiny is not set in stone for that, you can still change, people can change, so go fing her and tell her how you REALLY feel. Dont only think in the probabilities of failing, because while you have some probabilities of succeding, it is still worth to give your shot at big move like this... (something like that, can't think of something more epic/original)
Yuzu after some hours of looking for MInami, finds her, still crying, and Yuzu approaches her, making sure she hears her, proceeds to apologies for how she treated her and it was her fault, how I loved you so much that I tried so hard make your wish of being BFF to stay true, BUT I was the one who didn't want to grow up, I didn't want to change, I didn't want to be separated from you if something came between us. I never forgot all the things you did for me, you wanted me to be better and I just could thanks to you,Yes I love you and thanks for loving me back as you do... (details details).
If you, dear reader, have some opinions, I'm glad to read them! Have a nice day!
