The Tangent Lovers

At the age of five, Laetitia Marano discovered that she is suffering from a very rare allergy that changed her life forever. Her allergy is also the reason why she lost her parents-- well that's what she thought. But despite of living without her parents and having a rare allergy, she managed to live a normal life. But what will happen if she meets someone who also suffers from a rare illness? Someone who will make her realize that living with regrets is not living at all. Someone who will prove that tangent love is indeed the worst.
