Engaged to the Unidentified — Season 1, Episode 4: She's Just a Pervert

Episode synopsis

The morning after learning about Hakuya, Kobeni ends up with a fever due to her weak body. As Benio informs Mashiro and Hakuya about what she told Kobeni, she blames herself for Kobeni's accident back then, as she had Kobeni take her place alongside Hakuya so she could go and play. The next morning, Kobeni opts to stay at home alone whilst the others go to school, though Mashiro comes back to help her as soon as school ends, where Kobeni shows her the scar she received back then. The next morning, as Kobeni starts feeling a bit better, Hakuya suddenly rushes out of the house when he notices Kobeni struggling to face him properly. Kobeni catches up to him and states that, even though she doesn't remember anything, she owes him her thanks, becoming awed by his smile. Later that night, Mashiro and Hakuya receive a letter from their family, saying they will be sending someone to check up on them.

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.
