For the Sake of Dulcinea

From Evil Flowers:

Shin Soon-Ae has the perfect boyfriend in the eyes of her peers. He’s handsome, is in a band and loves her. One problem though- she doesn’t love him. One day, a boy appears and wants to board with her family as a student, and Shin Soon-Ae finds herself attracted to the boarding student. To complicate things, the boarding student seems to have strange mysteries of his own.

BACKGROUND: Dulcinea is a reference to Don Quixote, a Spanish novel about a man who is in love with a woman, Dulcinea. It also happens to be the name of the band Shin Soon-Ae’s boyfriend is a part of.
