I must say, for an author who was so focused in Dear My Teacher that the interesting side characters got spun-off into their own series rather than diverting attention from the MCs, this is pretty diffuse, and, in my opinion, the scenes are not as emotionally charged as I expected them to be.
Sure, the "uselessness" theme isn't as sexualized as the story in DMT, so the emotional stakes are inherently somewhat lower (i.e., people trying to break painful or destructive patterns of behavior there versus girls edging toward their first real romantic relationship here).
Maybe it's just that I am interested in the MCs and their individual and mutual development, and the others, for whatever reason, not so much.
