Bokura wa Koi ga Heta Sugiru

In order to shake off the hurt of being cheated on by her now ex-boyfriend, Hana goes on a trip with her best friend Mizuki. At their destination, the two meet a pair of guys, but just as they've started to get to know each other, it dawns on Hana that her troubles are the result of her own too-sweet personality. Now determined to better herself, Hana sets out to change her pushover ways...?! This is the hapless love story of a clumsy quartet: Hana, who's always sacrificing herself for others; Mizuki, who only wants to be loved; Narita, who earns others' ire when he tells them blunt truths; and Ayumu, who is kind, but also something of a playboy. Can the four of them get their acts together long enough to avoid stumbling over themselves? (Source: Manga Plaza)
