May is insane and has been since shildhood. This has led her to be locked up in an asylum for most of her life, which has made her gloomy. She has a love for books since they help her escape reality for period of time. It's from these books that her aspiration of becoming a gardener has come from, she heard of how amazing nature is and the freedom you feel from it. And that makes her wish to be as free as she can when she's finally let out. #asylum2es
