-Similar Harem Anime
-The main character has the same voice actor.
-Every girl has some sort of interest with the main character. She will do anything for him.
-We have a hot/popular, a childhood friend and many more to come XD
Both anime involve a harem of girls forming around a guy who doesn't really want a harem; both anime focus on comedy with some light drama throughout. Characters in both anime mostly fall into expected archetypes:
-Unnoticed childhood friend
-Verbally abusive rich tsundere
Also, both anime do a good job of making it unclear who the protagonist will ultimately end up with (a rare thing in harem anime)
