Sanzu Haruchiyo -Your tablemate.He has white hair and long eyelashes.You and everyone have never seen his face because he wears a mask.He is quiet and cold.You stay in the classroom after school when the students have gone home to clean up the class.When you are carrying a rather heavy bucket of water to class to clean up, it is quite difficult for you.Sanzu appeared and grabbed the handle of the water bucket from your hand and carried the water bucket to class to help you in silence."..."
