Lame, seens like they changed. On the novel his childhood friend left him thinking hes useless, here it seens like he left his childhood friend like a lame typical manga main character. Manga didn't have the balls, looks like the author here had that kind of mindset that the girl can never be bad and only the male protagonist can be annoying and insecure. Sad, I was hoping that type of revenge story when the girl regret thinking the guy was useless and abandoning him and see him happy with a cool another party.
