Both of these films have a commonality of showcasing the harsh, at times brutal realities of life, yet are not completely devoid of hope. While Better Days takes more of a romance angle, Orokamono no Mibun takes the found family angle.

Both are based on the same source - couple never met but have been married for 3 months and then have a ONS.

Mobius is less about romance and more on the mystery and sci-fi, but they both go in time loop. In “Oops!
