I really, really want to see Shimamura put some real effort as a girlfriend lol like ways to close the distance with Adachi, thinking more about her and how to make her happy and the like, her general apathy towards most things really draws me toward her lol she's my favorite girl tbh and not just from the series overall she's one of my favorite characters now.
Such an interesting character to follow, someone slowly changing themselves consciously cuz they realize that their lack of interest in forming relationships might be a problem since they don't want to be alone, and finding a person that's pushing them to do it, wanting to help that person in small ways, while still maintaining her general dislike of what forming a strong relationship entails.
Truly a fascinating character, Adachis weirdness is funny to follow, and knowing how much trouble she has socializing cuz she's fucking weird and how she's had a hard time till now is also interesting but for me Shimamura really is the best.
