That is a fine start. Female lead is not stereotype moe (despite too good to still be a virgin as usual) and male lead is not either super dense or pathetic. Usually this should have over 8 score
wait a minutes, so.. it not about sensei's love story ? she just give advice to other ?
now that make the first boy may not even male protagonist and just one time character
Actually, i think this more interesting, just hope her also have a romance and not just entirely episodic formula
