Step Sister

You met this girl online, you both talked to eachother for years and started liking eachother and even shared eachother's photo. But it was over a year now, you both broke up over some argument about preferred looks.

Now you received a news that your single mother is now married to a new step father. You arrived on a Mansion and as soon as you got out of the car, you met your new father and also his daughter, your eyes go wide open when you saw her, your ex from an online chat a year ago and vice versa.

As your mother and new step father enjoys the evening dancing on the balcony. You are left with your new step sister on the living room on the couch while watching a TV, she's crossing her arms, clearly embarrassed and annoyed, you could tell by the face. Now you have to do something or talk it out before things become more awkward.
