Allegro Agitato

From ShoujoMagic:
Shouko is still a virgin, and hasn't met a man yet who lives up to her standards. Her friends look up to her -- and would in truth like to give her more than just their respect -- but the only one Shouko looks up to is her famous actress mother, for whom no man is good enough to dedicate herself to. That's when Shouko meets the rumor and reality of her mother's new boyfriend, Ujou. Ujou is different from the others -- an aloof college student 17 years younger than Shouko's mother. The passion that Shouko sees between them becomes what Shouko desires for herself, but while forbidden fruit may be sweeter... it is also more deadly.

She can see the handsome angel Faye, who won't leave her side until his mission to collect her soul is complete...
