Yummy
The thing is, you dont want either of the two's behavior to come out on top
Its a good thing that adachi is freaking out, and its a good thing that shimamura hardly seemed to care about it, as it is also good that shimamura is causing adachi pain, because that'll just reflect back into shimamura in how the treat each other
Its about them both evolving, learning about their bad habits and tendencies through each other's. If one would just feed into another's vicious and bad tendencies, they would go nowhere.
Say shimamura takes Adachi's phone call to heart and never hangs out with anyone outside of Adachi's knowledge? This is the plot of like half the toxic yuris Ive read, you dont want that
But then say adachi is indifferent to shimamura's aloofness: then shimamura will never feel the need to go deeper into adachi, she'll be static in a point of comfort where she doesnt move anywhere, doesnt evolve. Cant build true connections with people and will always be stuck in her own mind
The fact their bad traits go against each other like this is best case scenario. I love this manga so much
