Should I read Never Understand first? Or do you think it will be fine to start this first,...

I guess its fine either way. Necer understand doesnt really play a huge part. But u may be confuse about the seme and his ex gf break up reason or y the seme apologised to the guy he was with in the latest chap. Regardless, it ia a gd story

I personally would. It will explain who some characters are and why Ayeon behaves the way he does.

Thank you!
