STROBE EDGE (Sutorobo Ejji), by Io Sakisaka. First published in 2007 and first published in North America in 2012.
PLOT:
Ninako has never been the kind of girl who knows her own thoughts. She's more the sort of person to go with the flow and agree with whatever ideas her friends might suggest. So when her girlfriends say that she MUST be in love with her old friend Daiki, well then surely she must be! She believes this until she starts to get to know Ren, the class idol. Bit by bit they start to open up to one another and Ninako starts to truly understand what being in love actually is like. Just as she comes to this realization, Daiki blindsides her with a couple of confessions of his own and Ninako finds herself more confused than ever.
