The Book Cellar
This is book number 1 in the Hafu Sans Halo series.
Haruna Mitsukai is an overachiever with dreams of attending the University of British Columbia.
Ryu Debiru is a bad boy whose only desire is to escape this ridiculous prison called "his life."
Both attend Shady Glenn Academy and despite their similar "hafu" identity, they couldn't despise each other more.
Years of avoidance come to an end when a major assignment on Shakespeare's Merchant of Venice pairs them together.
Just as everything reaches a breaking point, revelations about an old East Side mansion called "Heaven" causes Haruna to question everything she thought she knew about him and about herself.
As for Ryu? Well, all that glitters is certainly not gold.
