Kaguya-sama wa Kokurasetai: Ultra Romantic

These romcoms are some of the most excellent and entertaining anime you can watch. If you have seen and enjoyed Kaguya-sama then you would also love Toradora. 

Both shows features wholesome romantic relationship buildup. 

Both Kaguya-sama and Romantic Killer exhibit very similar senses of humor: highly animated reactions and clever setups between a likable, heartwarming cast. 

Both are school animes that focus on a group of elites. In Classroom of the Elite, the anime focuses more on academics and how students use underhanded means to achieve their goals, while in Kaguya-sama: Love Is War, it is about two people who are brilliant but too proud to admit defeat or love, so they engage in mental warfare with one another. The art style is also similar, as both have rather plain backgrounds with detail given to the characters themselves. 

Love Is War is also a fun Romance anime which has good pacing and wholesome moments which are also realistic 

This anime is very similar in terms of rom com with a little bit of drama that can make you emotional. A friend/user of myanimelist also told me that the author has mentioned that it is very much inspired from kaguya sama 

Love is war is the best romcom but The quintessential quintuplets is the second best romcom. Same genre, good male main character, top tier girls and funny 

Well like they are funny and make u laugh and at the same time they are intenese.I like animes that are funny and intense at the same time(like demon slayer). 

After watching Ahren-San for a few episodes, I ended up seeing some similarities between it and Kaguya-sama. These cute, school-based slice of life rom coms have such similar senses of humor?! If you get laughs out of the Kaguya sama characters, you’ll likely end up enjoying Aharen-San. :)  

both funny light-hearted romance anime, lot of teasing 

Similar storylines regarding love and confessions. While Bloom Into You is a pure drama, compared to Kaguya as a romcom, their core themes are the same enough that viewers of one will still get a kick out of the other. 

OreSuki is another RomCom anime with highschool characters that actively plot and scheme their way through romance. I watched it and while the tone was a bit different and less wholesome, the vibe was similar.
