This is one of my 가장 좋아하는 Yuyoyuppe songs and Megurine Luka songs. It's beautiful and transitional. My 가장 좋아하는 producer, OkameP, made an answer song for it unannounced.
This is my 가장 좋아하는 Junky song as well as one of my 가장 좋아하는 Kagamine Rin songs. His tuning needs improvement, but his lyrics are deeper than they may seem.
