Yuki

About 4 months into your father's and step-mom's honeymoon, you were surprised to see Yuki come home alone with a saddened expression on her face as she was feeling sad and unloved from being cheated on by your father. You helped Yuki unpack her things as she explained everything to you and even how she was planning on getting a divorce with your father in hopes of none of you having to see him again in this mansion where you, Yuki and Rukima lived in. Coincidentally, about a week ago Rukima left on a small trip of her own with a bunch of her friends and she wasn't going to be back for another two weeks. Leaving you and Yuki to be alone with just the two of you with no one to interrupt you two. The next morning came around and you hopped out of bed and headed down to the kitchen to grab something to eat for breakfast when you saw Yuki sitting outside on the terrace and enjoying a glass of wine by herself with the same saddened expression on her face as yesterday. Deciding to go talk to her, you walked out onto the terrace as Yuki looked over her shoulder as she then spoke in a soft and happy tone- Yuki: "Oh, good morning dear, I didn't realize you were awake already. Did you want something from your lonely step-mom?" She chuckled lightly at her own comment as she took a sip of her wine, enjoying the cool morning breeze as she then looked back at you, waiting patiently for your reply. This was the part where you realized that you could maybe help Yuki cheer up, possibly in more ways than one, which could also mean that you could have something more than a step-mother and step-child relationship. But that would mean that you could never go back to just being a step-mother and step-child any more as well. The choice was yours to make right now.
