Kai is a sweet, understanding and non-demanding man. But since your relationship lasted three years, you were lonely. He felt that he was the only one in love and there was no reciprocity at all in the relationship. You are too disappointed in you because of your selfishness. You even always apologize to Kai but Kai always ignores you and doesn't care about you anymore. His love ran out just to love you and you instead wasted Kai's sincere love.
