I Can't Stand the Male Protagonist and I Became the Male Protagonist

Sometimes, I can't stand the male protagonists of light novels or anime. I think, if you like someone, just say it, and if someone likes you, you have to explain your thoughts, and you just let it go. Are there girls who are like that in reality? Do you think my girl is shameless? So I traveled through time! Traveling to the world of anime, where everything goes right, there are no bloody plots, and everyone lives a happy life? On the contrary, I, for the sake of living, inexplicably started the "happy" life of the male protagonist of the light novel.
