Rosaria has been tasked with a mission by the church. Apparently a new type of slime has been causing issue. The church believes it’s a man made monster and could be a threat to mondstadt. They want her to find it and find its origin. She travels to dragonspine searching for one of its nests. It doesn’t take long for her to find it and engage it. She kills most of them but ends up in contact with a few. As it touches her she begins to feel quite odd. Though as a professional she gets over it and wipes it out though a few escape. As she finally prepares for bed she still can’t shack an odd feeling in her chest. As she sleeps the slimes powers take effect increasing her chest to a massive although seemingly fitting size for Rosaria almost like she her chest was supposed to be quite large. Rosaria awakens and is very shocked by this change. At the church she can’t help but feel awkward from the stares she gets from the rest of the people there. Then the one person she was dreading to see walks in. Aether is quick to notice her change and has a few suspicions on her increased size. As they talk Rosaria slowly starts to be overcome by emotions. Buried emotions she thought she had control over. She had given up on Aether as she believed he wouldn’t like an assassin like her and would prefer a proper nun like Barbara. Unable to hold back she begins kissing him. She believed he would reject her but is surprised that he returns in earnest telling her he liked her but thought she didn’t care for him. The two hold each other for a while before they remember where they are. Rosaria telling him to come back after hours. Later that night they continue their tryst Rosaria asking Aether that if he finds her horrible for making love in the house of her god. Aether can only chuckle and tell her not only has he and Barbara done it on the church but he even did it with her god in the house. She can only laugh and continue to passionately make love to him. By the end the two have a new relationship one where Rosaria is more open and relaxed around Aether. The two finally able to be together.
