I don't really understand the hate Haley gets for her banter and teasing with the MC. I read a conversation somewhere on this forum where people were talking about enjoying banter between MC and a love interest character, can't remember for which game, and was looking for other similar suggestions, and someone suggested this game, and the person complained saying they'd played this before hated Haley.
She's just teasing. She doesn't hate MC, she loves him. She never actually gets him in any real trouble with her teasing and banter. I don't get it, it's just her being silly. Know that she's not being serious, brush it off, and enjoy the story. I don't understand taking what Haley says personally.
