MC is trash and purposefully dense, the teacher is typical grooming abuser. I don’t think mc will ever get a clue, so our childhood friend should cut her losses and get with a cute blonde. Any luck it’ll be a grand daughter of yoru or if that’s not feasible someone who looks like her. That way when she happily walks by holding hands on the street, the trash teacher can be reminded that she’s terrible and abusing others for her past.
