Both have male leads who are single daddies. Both leads are from Sutato agency, the black rangers of their respective groups, Snow Man’s Meguro Ren (member color: black) and SixTONES’ Matsumura Hokuto (member color: black). Plot wise, well, very different. With Umi no, you’d probably cry every episode. With Sionji-san, it’s a total laugh trip. I’m still watching episode 2 but it’s really funny. It’s a good balance.
