Sendi originated from the tattoo on Sun's neck in "Dark Glory". One is Latin, which emphasizes the brevity and inevitability of life. It aims to remind people that life is limited and everyone will face death one day, so we should cherish time, live seriously and pursue what we really want to make life more meaningful.
Historically, death souvenirs have existed in many cultures, not only in art, but also in many philosophical and religious thoughts. It is a profound reflection on life and awe of death, encouraging people not to waste time and pursue more valuable and meaningful things with their lives.
Sun's ending
Wu is a thug of the five tyrants on campus. Although many things are not his intention, thugs will die because of many unjust, false and wrong cases. He could have had a chance after uniting with Wen Dongen. Unfortunately,-Wu can't see the situation clearly. He not only betrayed Wen Dongen, but also betrayed the other four tyrants on campus. Swing is the biggest villain.
Sun was confirmed to have been killed in the first season, and the truth and details of the killing were completely revealed in the second season. As expected, Park Yanzhen had a lot to do with Sun Mingwu's murder, but it was the waitress Jin Jinglan who eventually led to Sun Mingwu's death. In a sense, his murder helped Wen Dongen's revenge to the greatest extent, and it was also the beginning of the first domino dumping.
