The daily quarrels between a social fearful person and a social bully come from college life. It's not like enemies are forced to share a dormitory if they don't get together. Graduating in a mess amidst a bunch of messy things. After graduation, they buried the hatchet (can you believe it?) And became friends.
Purpose: Although life is hard, if you have anything to do, come to grandma. If you have nothing to do, don't come.
