Sono Kekkon, Shouki desu ka?

Kanane Shinohara's been in plenty of relationships, but they've never panned out. Now, she's in her mid-30s and has become incapable of falling in love. As she drinks her sorrows away, she convinces herself that the reason she can't find a decent man lies within her. However, before Kanane has a chance to fully accept her "harsh reality," a handsome man named Shirosaki appears before her. Has she finally met her Prince Charming? Or is there something more to him? Deep down, all Kanane wants is her own Cinderella story, but her experience tells her she's too old for fairytale romances. Using age as an excuse, she attempts to make a break for it and leave Shirosaki behind. However, he might not be so willing to let her escape his reach. (Source: Manga Plaza)
