Alright, vol 7. Keep in mind I've only seen the spoilers. By the way, in the forums I frequently a lot of people shed tears (bitch or true men's) for 8man during the events of 6 and 7.
First off, Miura's clique has Miura, Hayato, Ebina (fujoshi), Yui, Tobe (soccer club) and Ooka (baseball, virgin (seal of confirmation by 8man)).
The 2nd years have to go on a school trip, and during the school trip Tobe wants to confess to Ebina. Back in the Service Club, Yukinon starts to treat 8man better like making tea for him (it was always his job being the slave). Tobe, Hayato and Ooka visited the Service Club and requested their help to make Tobe and Ebina a couple, though Tobe changed his mind when he saw 8man (them rumors, fucking normals). With Yui's help Tobe caved in and made a formal request.
For the school trip it's mostly love comedy stuff for 8man and the rest, but he kept trying to convince Tobe that a failed confession isn't something you can easily recover from (8man has experience), Tobe brushes it off as 8man trying to be a nice guy.
Later, 8man met Yukinon outside (she's in a different class) and apparently Yukinon became revered as an "onee-sama" because of the cultural festival. Later, sensei ambushed the both of them and took them out to eat ramen.
The next day Tobe got closer to Ebina, 8man got closer to Totsuka and Yui, and Hayato was depressed the whole day. 8man took note of that.
At night, 8man went out by himself and met Miura, she told him about Ebina and herself, and didn't want anything to sour the relationship in her clique. Ebina never wanted a boyfriend even though Miura did a lot to help, and she suspected that someone might do something, though 8man told her Hayato would handle such problems.
Everyone, including Yukinon and Yui rooted for Tobe, but an uneasy 8man approached Hayato and asks him about Ebina, turns out that Tobe's confession will never succeed because of Ebina's circumstances.
