Seems Sven has finally learned how to embrace natural affection. He's grown to love Kyaw and appreciate his company. What other boy would give him such a heartfelt and unreserved hug. Sven looks happier and more comfortable and at peace with himself. He no longer needs to feel awkward about every little touch and physical contact.
Kyaw for his part finds Sven very handsome and loves putting his arms around him. His chest is warm, firm, and very alive. Sven no longer squirms and Kyaw is able to press right up against him and feel his wonderful body. As a roo Sven is probably naturally pretty strong and muscular.
Will they ever be together canonically? We will have to wait and see. I just needed to draw this for my own mental well being. It cheers me up.
