Reading some part again

Look, I love Cain character but, even as a love triangle, his part feels like it's randomly thrown in for fun rather than plot to the main character. The reincarnation had no value if you think about it now. And what even was the point of them sharing the same damn birthday?? Just felt like needless work for the author to give themselves.

Cain deserves better than having his own story become irrelevant.
