I remember listening to Fly To High by Younha, and around that time, I started reading the manhwa and I was in love with it. And when I learnt about the anime becoming a reality, I was so excited about this song being used, or maybe something as good by her. Contradiction by Tyler Carter sounds like a repetitive rip-off of Camellia's glitch-hop. Similarly, other manhwa series like Solo Leveling or Tower of God have opening themes I just can't vibe with.
