Fujiwara Hana and Katayama Mizuki have been best friends since elementary school. When Hana gets dumped by her boyfriend who was cheating on her, Hana and Mizuki take a trip together to relieve her heartbreak. They meet two guys – Narita Yosuke and Ichinose Ayumu – at a hot spring inn at their destination. Although they have only just become acquainted, Yosuke suddenly chides Hana, who does not have it in her nature to speak her mind. At first, Hana gets defensive. But she starts to realize that her inability to speak out because she is too mindful of others is a shortcoming and tries to change. On the other hand, Mizuki, who has never dated seriously before, wants to be loved. Yosuke is despised for saying things that he thinks are for the other party’s sake while Ayumu is a mixture of kindness and frivolousness. Then there is Ayumu’s “younger brother” Kanata. Friendship, jealousy, betrayal, and quarrels swirl in each of them. They start to come to terms with themselves through love.
