19歲的李杰明，是一個靈魂系的饒舌歌手，他寫的Rap總是貼切，一針見血，感情細膩，用深刻的文字描繪出他看到的社會。
但是他的敏感和故事常常被網路上的人攻擊，這首歌就是在他18歲時被攻擊之後不服寫下的一首純炫技歌曲。
發了之後果然得到了最多的注意力，他對這個狀態是又愛又恨；愛這首歌帶來的注意力，也恨一首沒有意義的歌得到了最多的反應。
儘管這是杰明的一個反擊作品，盛怒之下他仍然無比真實，帶著沒有人能忽略的饒舌技巧，這就是李杰明W.M.L。
19 year old William is a soulful rapper if there ever was one. His verses are intimate, yet hard-hitting and full of his views about society through his eyes.
But his sensitivity and knack for storytelling have kickstarted the flood of keyboard warriors; this song is the story of his experience with bullying when he was 18.
He released 'Mysterious' because he was trying to fight back through an impressive use of rapping technique, but after the song gained much attention, he begun to foster a love-hate relationship with it. Appreciating the attention it brought him, but hating the fact that a song borne out of no meaning could have such appeal. His skill, and his honesty are nevertheless displayed out and proud in this song, marking the first chapter of his story with SKR. This is William Marshall Lee, presenting 【Mysterious】.
