Senpai! Imakara Kokurimasu!

Synopsis

Once Koharu's favorite actress told her that a good woman never gets dumped. Ever since then, Koharu has lived a life where she neither failed in her confessions nor she got dumped. Koharu is extremely proud of the life she has led so far. Not her friends though. They are tired of this farce since they know all too well that she has only ever confessed to the boys who wouldn't be able to turn her down. Annoyed at her charade, they finally snap and challenge her to confess to Kanzaki, a second year heartthrob in their school, who has turned down every single confession with a smile and thereby earning a nickname—'the smiling guillotine.' Prideful Koharu decides to take up the challenge and confesses to Kanzaki only to be turned down even before she gets to complete her sentence. This cannot and shall not be accepted! Koharu refuses to back down and decides to keep on confessing until she gets an OK from him! (Source: MU)
