Background / History
Hasebe initially spends time alone at a secluded grassy spot, lying quietly beneath the open sky. Bai Ye joins her there, keeping a respectful distance; the two share the space in silence and agree to return the following day. Their repeated meetings become the foundation of their friendship 19 21.
As a child, Hasebe developed earlier than her peers and was teased by both boys and girls. The experience made her withdraw from close social relationships and distrust friendships she sees as merely superficial 23. Although she talks easily with classmates, she distinguishes casual conversation from the kind of friendship in which people can speak honestly and support one another 23.
After Bai Ye repeatedly joins her at the grass spot, she begins approaching him more openly, gives him the nickname “Little Yeye,” and offers to help with his worries 21. She later visits his dormitory to deepen their relationship, explaining that she wants him to become a genuine friend 23.
Appearance
Hasebe is a pretty, mature-looking girl with a notably curvaceous figure and a tear mole beneath one eye. Her early physical development was a source of unwanted attention and bullying during childhood 19 23.

Personality
Hasebe presents herself as somewhat cool and distant, but she warms up quickly once she considers someone a friend. She enjoys giving affectionate nicknames, teasing Bai Ye, and taking care of people close to her 21 23.
Her past bullying left her sensitive about her body and cautious about emotional intimacy. Despite this guardedness, she is proactive when she wants a closer bond, openly telling Bai Ye that she wants to deepen their friendship rather than remain at a superficial level 23 27.
She is protective and possessive toward Bai Ye. Her dislike of Horikita intensifies when she believes Horikita is treating him coldly, and she openly competes with Horikita for his attention 22 24 25. Even after learning that Bai Ye and Horikita are dating, she remains emotionally attached to him and struggles to conceal her disappointment 31 35.
Relationships
- Bai Ye / Jingu Byakuya — Close friend and the person Hasebe calls “Little Yeye.” Their friendship develops through repeated meetings at a secluded grass spot, shared outings, teasing, and mutual trust.

- Horikita Suzune — Romantic rival. Hasebe resents Horikita’s cold treatment of Bai Ye and clashes with her over eating lunch and spending time with him 22 24 25. She is upset when Horikita publicly declares that she and Bai Ye are dating 31.
- Sakura Airi — Friend. Bai Ye recommends Sakura as someone compatible with Hasebe, and Hasebe later succeeds in befriending her 23 35 49.
- Ichinose Honami — Hasebe envies Ichinose’s apparent ease in gaining friends and wonders whether her own guardedness is excessive by comparison 25 27.
