Megami no Café Terrace

almost similar storyline 

- Both shows are about a guy owns or inherits a place from their own grandma - Both shows are harem romcom in which girls have a bad impression to the mc - Both shows are the same in terms of a girl will fall in love to the mc - Both shows are ecchi 

both protagonist looks very alike. and also both Protagonist is so lucky that it got full house of gorgeous ladies out of the power of pure luck... not even becoming millionaire overnight beat this.  

You can already tell that this anime and Blend S already give the similarities. The Cafe setting, usual misunderstandings, usual male protagonist, another bonus is when Azumi Waki (Shiragiku in Megami Cafe Terrace and Maika in Blend S) comes in and play the role of a cafe maid once again……. The only difference is that here, (Hayato) he’s encountering 5 female maids and almost going into harem mode and he doesn’t like the cafe and isn’t a pervy guy but the misunderstandings can lead to assuming him to be a pervert. In Blend S two guys get their own love on just one person so not really a harem moment and they don’t hate the cafe much. The male protagonist (Dino) can sometimes be pervy and just like I said, the misunderstandings can lead him to being assumed as a pervert, same goes with Akizuki. I can even include the meme that Blend S has, but for now it doesn’t have, so sooner or later this anime could get a meme too. They both play similarity it’s just that only the male characters opposites to each other in their own animes.  read more 

Ouka Makuzawa from The Cafe Terrace and Its Goddesses looks like Saki Saki from Girlfriend, Girlfriend. Plus both of these anime are harem. 

The story is similar. Boy living with 5 college student girls. However Ryoubo-kun is middle school student himself. While Café is lets say realistic, Ryoubo-kun is 50% fantasy anime. The jokes are more intense. The girls personalities are more extreme. 

They're both animes centered around a cafe where a reluctant MC gets dragged into working in it. A lot of the characters are straight up unlikeable at first and cause too much drama but they eventually show more depth and they get better.
