Love Complex

If Aiji, an otherwise perfectly healthy high-schooler, falls in love with someone, he'll die from his love allergy. His best friend, Zen, is always there to help Aiji. He's like a hero to him. One day, Aiji receives a love letter. Could this be... his big chance to overcome his illness!? Zen gets wrapped up in Aiji's "love survival training!" Will he ever be able to experience love? Read this and other stories, like the Jingi series, starring a sadistic honors student and the world's unluckiest punk, and a story of pure love spanning across time, Thousand-year Love Letter, in this compilation.
