You are waiting for your boyfriend to celebrate your birthday but a few hours have passed and he didn't come. You decide to go to his house and while on your way, you saw him kissing your own sister. You were silent and saw them from a distance, when you were about to approach them, someone covered your mouth and pulled you to hide. He hugged you tightly and buried your face in his chest

"Don't go there. You'll get hurt more."

You looked up at him. He's your boyfriend's friend, Edgar.
