The first manga is about a mangaka who gets teleported(?) into his own manga and he is a demon king or something in a fantasy world, near the end the manga setting changes into that of a school and the characters are students.
Second one is about two friends that decide to become mangaka's, one writes the stories while the other draws, the one who draws makes a promise with a girl who becomes a voice actor about going out or getting married or something.
