Tokidoki Bosotto Russia-go de Dereru Tonari no Alya-san

MC has same personality. Most attractive thing is both MC don't get shy easily and can make conversation with girls properly. 

Similar character dynamics, characters in general are very similar, the type of humor is super similar, identical setting, and the different characters’ backstories are very similar (aside from the whole revenge plot line in Masamune-Kun). The only difference between these two shows is that the MC of Masamune-Kun has a plot related reason to get closer to his version of the Alya and that Masamune-Kun has more exaggerated humor, but aside from that the two shows are almost entirely identical; truthfully speaking, Alya-san is the better anime but both are a fun watch and if you enjoyed watching Alya-San enough to look for anime similar to it then I recommend watching Masamune-kun read more 

Both are romcoms with incest vibes. Both series have a degen girl who gets along with MC better than the tsundere main love interest. In Roshidere this is the sister, while in Tsurekano the sister is the main love interest. 

- MC are capable, and handle situations seamlessly. They also kinda lazy. - MC are NOT clueless / dumb. - "Harem" but everyone feel like individuals rather a character that chases or gets chased by the love interest. - Each girl have their own story / arc with the MC. - 2 of the Girls are sibling. 

-both has silver haired heroine -both heroines are popular girls -Both involve girls coming into mc lives -Both a rom-com type of shows -both have a popular girl, a childhood friend xD
