I think she is the girl in the rumors. Maybe when she said "i lost again father" maybe because her father owns the school ? And maybe she said sorry because she kept repeating her grade (seems like the rumor is been passed around for a long time now) the because she gets distracted to cute girls. ┑( ̄Д  ̄)┍
