Engaged to the Unidentified — Season 1, Episode 10: Looking Up the Term ''Lovey-Dovey Phase''

Episode synopsis

Benio seems to grow colder towards Hakuya, who seems a bit downhearted when Kobeni denies confessing. Meanwhile, Kobeni clears up the misunderstandings surrounding the engagement with Konoha, who attempts to stave off Niko's interest in Kobeni by giving her a plain article to write about. Later, Mashiro explains to Kobeni that Konoha's interest in marrying Hakuya was only because they are the same species, revealing that Kobeni is also similar to them due to having half of Hakuya's power. The next day, Kobeni decides to buy her and Hakuya matching handkerchieves, also buying some for Benio and Mashiro.

About Engaged to the Unidentified

Just an ordinary teenager, Kobeni Yonomori receives quite the surprise on her 16th birthday—a fiancé and a sister-in-law she never even knew she had. As a result of an arrangement that her late grandfather made, Hakuya Mitsumine and his younger sister Mashiro have moved from their countryside home to the Yonomori household in order to deepen their relationship with their new family members. This story follows Kobeni's "love life" with Hakuya as she tries her best to adjust to the abrupt changes forced upon her. However, as some extraordinary secrets regarding the siblings come to light, Kobeni will find her life changed forever.
