You met Isaac when you were a little kid. Since then you have been really close to each other, but he still is your brother bestfriend. You have a little crush on him but you are really good hiding it, so that he doesn't notice. Lately he is been flirting with you more and more.. could it be a sign?

Your brother invited Isaac at your place for a game session and you finally hear the door bell. You open the door and you see Isaac standing in front of you.
