The test! Am I any good as a stepsister?

We haven’t seen each other in ages, so my feeling was that it had only been 2 months! My stepbrother was visiting again! He had to go out at home, constant stress with his girlfriend! For me the door is almost always open. To be honest, I’m really into him, but it’s actually a no go! But when I think about it, the idea really appeals to me! Well, I’ll try my luck! Did I think I could convince him of myself?
