Both are Japanese GL(Lesbian Romance from Japan). Both are a romance series but both also deal with some serious subjects too, however Ayaka-Hiroko is more of light hearted comedy and Call-me-by-no is darker and more serious in tone. They share one producer that worked on both series.
Both have Lesbian romance. Both are gl. Both have an age gap, although it is a smaller age gap in The secret of us. Both have a career woman that is pursued by a younger woman.
they both have a similar vibe i think, ayaka chan is a more straightforward lesbian drama whereas futari monologue is a fruity-ish friendship but both have a girl that changed her appearance (blonde + contacts) to look cooler in the eyes of the other girl that they like.
they both have the same quirky, lots of inner monologue freak outs that are common in japanese comedies so i think if u liked awhsnk you will like futari monologue :3
