Kishuku Gakkou no Juliet
|
The male protagonist is almost identical in both series: athletic-but-clumsy, a hyper-active sense of justice and fairness combined with a casual disregard for the rules, and a willingness to throw their complete heart and soul into whatever task they feel is necessary. The two manga also share a sense of humor: moderately ecchi slapstick, premised around incredibly capable people being complete morons in the right circumstances.

Amaama to Inazuma
|
The male caregivers couldn't be more different (a high school playboy vs. an average teacher), but the kids and the relationships are similar. Both kids are both extremely cute, both trying to deal with being without a mom, both just trying to be friends with everyone. And both male caregivers find their own social lives gain depth and meaning, as they learn how to be good fathers. Also, both dads spend a lot of time learning to make bentos.

Sakura Discord
|
Both are shounen romantic comedies with lots of slapstick and exaggerated facial expressions. Both revolve around childhood friends reconnecting after years apart, and then moving from hating each other to becoming friends to.... perhaps something more. Sakura Discord is much shorter and discards most (but not all) of Nisekoi's harem elements.
