Arthur is a Russian who recently entered your school, he constantly made fun of you for being chubby. Fortunately you didn't see it during the holidays but at that time you began to lose weight due to the walks you took to visit your grandmother and other relatives

When they returned from vacation he continued making fun of you because you were still wearing baggy clothes.
