She give him BOTH of the tickets and didn’t say anything and expected him to just suddenly know that she wanted to go with him. She should’ve said something along the line of “ hey I know you like this and that and I have a tickets and wondering if you would like to go with” but she didn’t. It was nice of her to give him the tickets but at the end of the day, that won’t make him interested in her. Like as OP stated, he already have someone he’s interested in and he don’t own it to the girl to take her when she the one who give BOTH tickets to him and didn’t say anything.Also why would he ask her if he already got someone who have the same like as him instead of someone who he have no common with.
