In this narrative, set in the Fullmetal Alchemist Brotherhood universe, we follow Ren Jinhai, a Xingian prince and prodigy in the art of Alkahestry. The story begins with Ren’s life, whose interest in human transmutation is triggered by the death of his mother when he was eight. Although Ren eventually realizes the impossibility of resurrecting the deceased, he develops a unique ability to enter the Truth portal through meditation, allowing him to perform remote transmutations without a matrix. Ren’s character is defined by his compassion, empathy, intelligence, and unconventional worldview.

Due to the pressures from the succession conflict in Xing, Ren travels to Amestris to expand his knowledge. Upon arriving in Rush Valley, he coincidentally stumbles upon Winry Rockbell’s shop and seeks her assistance. Winry becomes intrigued by Ren’s passion for learning, and their shared love for automail and alkahestry strengthens their bond. They spend the day exploring the bustling town together. While working on a project with Winry, Ren opens up about his past and Winry can't help but compare how alike yet different he is from Edward. As they collaborate, they find themselves drawn to one another and eventually share a passionate kiss.

Following their impassioned moment, Ren transmutes a spare wire from their work table into a beautiful necklace for Winry, symbolizing their shared passion for knowledge and newfound connection. Ren’s hands explore Winry’s body as they continue to share passionate kisses, both of them wrestling with their desires and the decision to fully embrace the depth of their intimacy. Encouraged by this new connection and the intense feelings that it evokes, they let go of their doubts and insecurities, choosing to pursue this path together. In an atmosphere filled with the scents of sweat and oil that permeate their surroundings, Ren and Winry’s bodies interlace and envelop each other in the heat of their passion. Ren's hands explore her body as they kiss, from her shoulders down to her ass, then up her belly to her breasts over her crop top.

Exquisitely describe the feeling of her breasts in his hand as the kiss continues, remembering this is the first time for both of them.
