As result, she has conceived a child, Ashley, who was later told that she shared the same eye and hair color as the man who had kidnapped her mother. She wears glasses and an Alice band that use the power of magic to make her look disagreeable in others' eyes, and thus gets called an "ugly four-eyes." Unable to make any friends, Ashley used to lead an academy life of loneliness and solitude…

However, after her encounter with a mysterious creature, the crown prince grows interested in her…?

From MangaHelpers:

The story begins with regret, chaos, and desperation. Sora lives with his little sister, An, and his rather comical father. An is the soloist of her school's chorus, and Sora is an awesome cook. Sora prepares his "honki" (serious) bento for his sister's school concert.

Once An begins her solo, a mysterious force creates a rift in reality, as An's existense shatters right before everyone's eyes. Sora runs in to save her, but he too becomes part of this dark ritual. As Sora ends up transported to a fantasy world full of gigantic mushrooms, nothing can be certain on what will happen to these two.

Mogami Himoto shouldn't have any problems. He's rich. He's smart. He's athletic. He's incredibly attractive. He's an "ikemen."

Meeting Yaenami Yukka plunges his life into chaos. First, she mistakenly accuses him of molesting her and broadcasts the news to the whole school. Then she ropes him into pretending to be his fiancee... which might not be so bad if not for the self-defense mechanism which results in her punching any ikemen who comes close to her. And then there's the curse...
