This idea of this drama originated from an Original Musical project in the “樂戰九” competition held during the first semester of my study in the Graduate Institute of Performing Arts at National Taiwan Normal University in 2019. The author was the one who was in charge of that project. The creation of this series of script was developed based on the assigned theme — Comedy given by the instructor Professor Liang Chi-Ming. The process included a month of construction, two amendments of the outline and three revised versions of the script. Ten actors and three instrumental performers participated in an approximately two-and-a-half-month rehearsal, and that was the making of the 30-minute original musical “365 days of missing you”. This musical was developed into a 45-minute version and had been performed orally after being revised in January. The first chapter of this article is the introduction. The second chapter connects the storyline with what happens in the society. It leads into the core of the story through the current LGBT movement and the background of same-sex marriage in Taiwan. The first section of the third chapter describes the development of the drama and brings in the analysis of writing a well-made play through the step outline. It also sums up what had been proposed in Thinking like a director by Michael Bloom (2001) and The director’s Craft: A Handbook for the Theatre by Katie Mitchell (2009) of what a director ought to do. The second section of the chapter delivers a target analysis of the characters and scenes through the background information of the characters and the actions of the main character (林達) in the play, so as to understand the connections of cognitive goal, actions and obstacles of the characters in every scene. “365 days of missing you” is a play in which its leading character has contradiction and struggle facing family and the judgement of the bystanders in a same-sex marriage. The plots are complicated while reflecting the reality, and the personality of the characters are so distinct. After four performances, this play was awarded Best Performance voted by the audiences. This is also my motivation of keep revising and directing this play in the hope of making it a more sophisticated and completed piece of art work.
