I love how the author manages to juggle multiple interpersonal problems at the same time.

Haruka is about to disappear and probably has a crush on Shiki

Sudo asks Shiki how he'd feel if she and Shuji were dating. (Which kind of implies that Sudo actually liked Shiki, not confirmed though, but that would explain why she was hesitant in accepting Shuji's confession and this sad undertone whenever she talked with Shiki about it... Needless to say, Sudo X Shiki would never work because Sudo would have most likely fallen for the fake persona of his. It was shown in Vol1 that he and Sudo had a rather good relationship, with them bouncing of each other. That stopped after Shiki revealed that he was just pretending to avoid being hated)

Akiha is still afraid of Haruka stealing Shiki from her

Shiki insists that he likes Haruka but that last kiss in volume 1 was unkown, he can't figure out if it had been Akiha or Haruka
