It's hard enough leaving the love of your life behind, but it's even harder coming face to face with him again under less than desirable circumstances years later. Young and Vulnerable follows the story of Jean Kirschtien, who has been desperately in love with Eren Jaeger since college, and his struggle to come out of the closet. Or that story in which Eren and Jean meet again and Jean keeps trying to get in Eren's pants, but Eren is dating Levi and Jean just got married to Mikasa.
