Otonari no Tenshi-sama ni Itsunomanika Dame Ningen ni Sareteita Ken

Both are similar in the fact that they're both wholesome romance stories about a guy and a pretty girl. 

Both are very similar because the MC changes resulting from the relationship he is in and overall grows his character by the end of the anime. 

Slow paced, very cute and adorable boy meets girl romance stories. Both feature the main characters becoming closer and falling in love quite early also them living together/spending a lot of time together every day. Lots of SoL and Iyashikei elements as well. 

Similarities: -both living in the same area -romcom & school archetype genre -the story happens during winter (christmas feels) Difference: -the heroine (the first one gives "dandere" vibes, while the other gives "tsundere" vibes 

Living together without being on an actual relationship? Beautiful girls? Slice of life type of romance anime that has an incredible character development? YES! These both animangas shows so much improvement between two main characters who doesn't even like each others specially.  

In both series, there is a MC that seems incapable of doing anything without the main girl, where she sometimes acts more like a mother figure to him than a romantic interest 

If you like anime where love flows little by little, I think you've come to the right anime. Surely we will see how everything evolves little by little and everything is increasingly purifying for your soul. Because we all wanted to be that cool, professional gamer and get that cute girl to be our girlfriend and play our favorite game with us. Surely you feel identified with this anime and more than one will identify. Two people who don't know each other or hardly know each other start to become something more little by little? We will surely find out with the next chapters 

This anime also highlights the romance that develops from relationships between neighbors. 

Both of the female mc's go out of their way to do things/give things to the male mc's. 

Both are fluffy shows, with sweet characters. The friend groups for both a similar and are very weird and supportive. If you enjoy becoming a romcom diabetic, they are both very very good. 

Both of the series feature a beautiful deredere girl helping a shut-in, a-social, but inherently a good dude to get better; building a relationship in the process. 

Both will certainly give you diabetes from the sugar content, love and affection, and the amount of sadness you feel when it ends and you see a black screen, with your reflection, staring back into your soul. If you love either, you will love the other. Happy watching! 

In this anime, the main characters try in every possible way to take care of each other, support, pamper and protect. I think it's perfect because according to the plot they are burnt. 

These shows give off the same energy! Blonde-angel-popular main protagonist and her weird cool love interest. Oroka na Tenshi is the more chaotic and funny version while Otonari no Tenshi is made for people with mommy issues! hehe just kidding.. unless 

Both are about a blossoming love story between a normal high school boy and a rather mysterious girl. 

Both animes are really cute and wholesome withe the cutest adoeable girls. mc lives with the girl and can't live without her. 

Wholesomeness, lots of it. Cute couple doing cute couple things.  

just after watching the first episode of this anime, I got the feeling this anime heavily represents the feature of clannad 1. both main girls in both anime are quite similar, they are caring 2. both guys similar as well with one useless guy friend, both guys are lazy, have lazy lifestyle with unhealthy routiene 3. highschool based romance drama, where girl is caring and guy is lazy bum, 

Both are nice, fluffy and iyashikei-kind animes  

Both of them are an unpopular guy and a popular girl. The guys are both not really convinced of themselves and have a gloomy mood. In addition, it is about teenage love.  

Both are S tier romance that build up slowly throughout the episodes while focusing on the two leads. They are heartwarming stories with some good comedic moments. Both male Mcs have a past that influenced their behavior in the present whilst the main girls take up the first step to make their love happen through enchanting words and actions. 

Both feature two teenagers meeting and slowly falling in love with each other. Also similar slow pace with a relaxing atmosphere and a cute artstyle. 

Both of these are wholesome and fluffy romances with really "pure" FMCs. 

Both series involve the main leads slowly progressive into a wholesome and idealistic romance. The main male lead for both series is blunt and straightforward, with little to no filter with their words. While the main leads for both are highly supportive, friendly, and somewhat possessive of their main lead love interest. 

Same kind off story with an Loser protaganist and a cute girl by the same studio 

Both are rom-coms where the female main characters are really good at academics and looked at by everyone as the perfect role model students but have different sides in private. Both have the main characters meeting and beginning to get close early in the series, proceeding to spend a lot of time together. Both have main characters who have mental trauma (explored more deeply in Kare Kano, especially the manga.)
