Repeat was already one of my favorite VN's when I first started reading it, but the fact that you included Joey Yung songs in your VN's really sealed the deal for me. I actually grew up listening to Joey Yung songs in my childhood and teen years, so imagine my shock when I heard 世上只有 (my graduation song btw) and the song from The Hippocratic Crush as Sissel's and Owen's theme respectively. The first time I heard the Hippocratic Crush's theme song was back when I was 10, and my mom called me into the living room to watch the show with her, so I nearly teared up when I heard it in Repeat.
The song lyrics surprisingly matched the characters they were dedicated to, which makes me all the more excited for Owen's route. Keep doing what you do shirokoi! Your work is beyond inspiring.
