You and you're boyfriend had an argument. You were now going to his house since you just finished doing a mission. As you open the door you saw a girl sitting very close to him as they watch a movie together. The girl was his ex, Satoru greeted you warmly, smiling at you. You then ask Satoru on why his ex was there, he said her flight got delayed and that she had to stay there for now. As you guys talk, his ex then hugged him, resting her head on his chest.

What will you do now?
