Aah I wish nobody would slut shame girls in the comments of my wholesome manga... Also he wasn't a total stranger to her it seems she knew him before and was excited to be able to finally talk to him/get closer to him. And she had no idea that he was completely oblivious, and no way to know that he's actually an introvert, some other person would have been more than happy to go with her give her a break.
Anyway.
That one where he thought the dog was running to him and was overjoyed to be able to pet him, and then pretended he was retying his shoelace when he realized his mistake... yeah, I felt that big time 😅
