Angel Densetsu is a shounen while Ore Monogatari is a shoujo so their focuses are a bit different: one focusing more on juvenile delinquent comedies, while the latter focuses more on romance. But both series are about an intimidating looking, but kind-hearted young man wins over friends (and a girlfriend!) while primarily employing misunderstandings to keep the conflict and comedy going.
Both protagonists are misunderstood guys with hearts of gold who eventually find a girl who can appreciate them for who they are. Both use misunderstandings about the protagonist, based on his appearance, to drive the comedic elements of the story.
If you are looking for a different sort of shoujo, one with a male mc that is not a bishounen or from a guy's point of view, try My Hero! or Ore Monogatari!!. The guys in these shoujos are not like your guys in typical shoujos, in fact, they are sort of like the "other guy" or the sidekick guy in a shounen, they are Not handsome and not your typical shounen or shoujo hero. These male mcs are like the other guy or the guy who is a lot nicer but who usually does not get the girl in those stories. They are brave and forthright and honest. I think that Male readers, guys who want to chance a shoujo or who want a male lead who is not like those in either shounens or shoujos would like these.
And girls if you are tired of shoujos with bishounens who treat the girl like crap and have her fall for them anyway - READ these!!!
Oh yeah, they are Funny and Well written!  read more
Both are shoujo manga where the male lead is a not so good looking (and even that is a euphemism for describing Takeo) clumsy idiot who cares for the female lead, rather than a stereotypical shoujo manga male MC who can do everything but treats others like shit. Both are straightforward romances which emphasize the depth of feelings and love, and are satisfying and refreshing reads.
Both Densha Otoko and Ore Monogatari start off with the main protagonist rescuing a woman on a train, but while Takeo is a huge man, "Densha" is a nerdy otaku. However despite their dissimilar backgrounds, both guys are really "pure" in their intentions and bashful when it comes to dealing with the opposite sex and both seek out the advice of friends on how to manage and improve their relationship - the twist being that in "Densha Otoko", the man "Densha" recieves his advice from a popular 2chan message board (the story is actually based off a number of threads that really appeared on 2chan).
These two stories have a similar setup, two male leads that are shy and bashful romance novices, two female leads that are sweet and adorable and a similar light and fluffy romance tone that is just happy to read. If you enjoyed these aspects of Ore Monogatari then you'll probably enjoy Densha Otoko as well.
Both stories make readers happy, as well as reflective. Besides the characters being in high school (therefore, having events like school trips and school festivals), these stories depict non-generic characters. There is definitely diversity among the characters, and various situations. You see how people who are in love do their best, in their own way and own pace. There are fabulous friends who encourage and help each other. There are close friendships and tight bonds. Both sexes work for their love. There are no stereotypical gender roles pinned to the perspectives that the stories are told from, as the characters learn and grow through their choices and experiences. Both stories have their hilarious moments and are very refreshing to read. read more
Both of these stories feature protagonists who don't fall into the typical shoujo manga stereotypes. Physically, the hero/heroine look like characters that would be thrown away in the background of most other manga (a guy who's huge and intimidating in Ore Monogatari and an overweight girl in Pochama ni). They each have a supportive friend and manage to find the perfect partner who can accept them completely. I find myself enjoying them in the same way: for the refreshingly straightforward manner the characters have of facing their own challenges and romantic developments.
Both Manga have a similar ambiance. While reading Ore Monogatari I kept remembering Orange and it made me want to read it again. Although one is more serious and one is more comedic, both are about highschool friends trying to help one another, with romance and drama involved as well. I think if you enjoyed one of these you are likely to enjoy the other!
Despite their different premises, I find Ore Monogatari and Ocha ni Gosu to be similar especially with the relationship dynamics. Both series' main male protagonist are treated in disdain because of their outer appearance. Yet as we learn more about them, it's easy to realize that they have a big heart. There is evident romance development as the story progresses and reaches many points where we see the real personality of the characters. Recommended for fans of rom-com.
The feeling while reading both of them is the same.Lots of comedy and romance.
The main characters, Risa and Takeo are very similar : ridiculous and complexed by their appearance (Risa is taller than her crush while Takeo has unappealing figure and a huge constitution)
Inexperience in romance. Both series' main male protagonist falls into that category when it comes to developing relationships. Throughout their past lives, they have been rejected by girls for various reasons. In present time, that pattern seems to continue but some events unfolds that changes that. Both series are known for some cliche story developments but remain genuine to their premise and intentions. There's also a good amount of characterization as we see what our main male protagonist is really like; although their personalities aren't very similar. Recommended for fans of comedy/drama/romance.
