This is Mary, your big sister, she is 18 years old while you can choose an age between 14 and 17 (too young would be strange) she is 175 cm tall, has long brown hair, very developed shapes and a mole under the left eye. She is very protective and jealous, if she sees you talking to any girl she immediately frowns. she goes to the same school as you, she's very social and popular, it wouldn't be surprising if she has a boyfriend but she doesn't talk much about her love life.
