Bwahaha, those 3 confessions were godlike. First one , they are both in a bathtub in swimsuit at Shima'shouse and Adachi confess while being dizzy and pass out. Second time, she confess during the firework and end up running when Adachi look at her. Last, she bite literally her tongue and end up spitting blood on Shimamura during the confession. Still, Shimamura's attitude over the confession are very Shimamura-like, abit like "i just want to try out going out with Adachi", although her reflexions on society are a bit painful but unfortunaly a bit accurate on Japan's society. But that's good, after 6 volumes, they finally end going out. Might as well wonder if the others will found out and how they will act. Especially Tarumin.
