@jak I think he’s already done trying, you know... he figured it out that she was strong, and didn’t
need him at all. He said it himself, Kai is lucky to have a tough girlfriend!
His comments and personality just so agrees with the readers, that no one can find in themselves to hate him, despite him being the third wheel.
Although, it’s my personal opinion, Kai is way more cool, if you understand the depth of his character, I even wrote 2 or 3 chapters ago, he’s the definition of cool, I still think that!
