Utsubokazura no Yume (2017)

Description:

18-year-old Saito Mifuyu is a simple girl who grew up in Nagano. After her mother’s death, her father brings his lover over which displaces Mifuyu in her own home. She arrives in Tokyo following an invitation from her late mother’s younger cousin Kashimada Naoko to come over to her house for a while. It is a house blessed with “wealth” that she herself cannot obtain even if she wishes for it. Thinking this outrageous, Mifuyu starts seeking to fit into the Kashimada family, and in the process completely changes into a “pitcher plant girl” who plays on the desires of her prey to attain her goals.
