Doubt!!, Volume 3 Book

Just as Ai begins to feel secure in her budding relationship with Sô, she hears a rumor that Sô isn't solely devoted to her. She doesn't want to believe it, but when one of Sô's other girlfriends--a beautiful, elegant college student named Kyoka--arrives on the scene, Ai can no longer avoid the truth and is thrown into a tailspin of confusion. Was it naive of Ai to think that Sô could only have eyes for her? Is she ready to swallow her pride and compete with Kyoka for Sô's attention? Or will she decide that no guy--not even Sô--is worth the hassle and humiliation of sharing him with other women?
