She is so obsessed that her parents forced her to either give up her hobbies permanently or get a place of her own (which she did). She often has to eat cheap ramen as she spends most of her money on so much paraphernalia to the point that it clutters up her apartment and she cannot invite anyone inside without them discovering her hobby. Much to her humiliation, Yuzuki is a virgin. In the manga, Yuzuki and Keita eventually become closer, admit their mutual feelings for one another, and start dating in secret, a fact only known by Ako and Riko (but eventually discovered by Mikazuki and suspected by other characters), who despite being angry at her for getting involved with her own student, respect his decision, stating that in the end he will return to their side.
