   Summary

   For Ana, a logical Black Cat Omega who finds more comfort in predictable code than in people, the world is a series of algorithms to be solved. Touch is an error in her system, a variable she has avoided her entire life. For Kim Chaehyun, a world-famous White Tiger Alpha, life is a carefully managed stage, her instincts a quiet hum beneath the roar of fame.

   In the silent stacks of a university library, a new scent overrides every system. Petrichor and vanilla. Tiger and cat. When their eyes meet, the soulmate equation solves itself instantly, leaving Ana's rational mind in ruins. The result is undeniable, primal, and everything she has ever been afraid of.
