叶野 夢

Yume is the younger sister of Seiji, the younger cousin of Yurari and the childhood friend of Karin, Jun and Atsu. Later, she becomes the friend of Mitsu.

She has a very fragile health and only goes out for her extended stays in the hospital. She spends most of her life confined to a room.

Exiting very rarely outside, Yume has developed an unmeasurable passion for programming. Often alone at home or with her mother, she has developed an instant conversation app (named UNI) so she can talk to anyone she loves at any moment.

Yume is romantically in love with Seiji because he has always taken care of her and has always prioritized her. She hopes that Seiji will one day be aware of her as a woman, but she is quite complexed because of her cousin Yurari, who often comes to their house, and who has a lot more assets than she so she treats her as her rival.

Yume is so talented in computer science that she has been noticed by some companies. She hopes to one day open her own business and earn a lot of money to benefit her family.

Yume's doctor found that she is sterile, only Yume's mother knows it and she is briefing Seiji because she is afraid of the day when neither she nor her husband will be able to take care of their little treasure and she asks Seiji to take over the day they disappear.

Her parents consider her as a small treasure: pretty, attractive, charming and bright but fragile./
