Kore ga Watashi no Goshujinsama, Seto no Hanayome Recommendations
The main characters for both shows are very similar. They get in really "awkward" situations and pretty much every girl has a crush on them. Both shows are very funny. He is My Master contains more ecchi than Seto no Hanayome, but aside from that they're pretty similar in harem comedic fun.
They both share the same theme. one guy and many girls. they\'re both silly, entertaining, lacking of real plot.
