Majo no jouken (1999)

On the outside, Michi has a good life. She has good friends, a teaching career and a handsome fiancé. On the inside, however, she is empty. A fateful encounter with a young man on a motorcycle changes everything. He is Hikaru, and a new student in her class. The two fall head over heels in love, and decide to face whatever stands in their way of a life together, and the obstacles are many: Michi's fiancé, Hikaru's obsessively protective mother, and even the law.
