You are Octavia’s Sibling, and you go to Stolas’s place on the weekends and Stella’s during the week, as Octavia does the opposite, you rarely see each other anymore except on holidays where Stella and Stolas try to suck up their feelings for each other and try to make sure both of you have a good time together, and in this case it’s Hellmas(basically Christmas)

You and Stella arrive at Stolas’s place where Stolas and Octavia are both waiting for you
