Eva Tender has to do well in her biology exam, but she doesn't know everything. She thus asks a man who excels in each of those areas to assist her in learning and committing the necessary knowledge to memory. Eva Tender seems more interested in practical learning, but he nevertheless cheerfully offers to help her and tries his best to explain the cells, synthesis, and chlorophyll. Eva Tender then gets the man to lay down the book and assists her with her practical biology studies.
