wait, is this a series you have forgotten about or you want recommendations? if so, two series that might be what you're looking for: Lost man Area no Kishi
________________ kyoko: but you're a good liar...you really are a play... ren: I wouldn't tell a lie to trample all over a woman's heart kyoko: and sometimes, you're needlessly kind... ren: what's wrong with that? kyoko: con artists are good looking, kind, and smooth talkers... ren: who's a con artist?!
Its something I forgot. Its not Area no Kishi but it has a similar setting somewhere in between the series. Its starts out with a broken down team and female lead becomes like a team manager because male lead is part of the team.
Better yet name all the manga you can think off that start with a broken down team that gets rebuilt with the arrival of a new student.
