Sekai-ichi Hatsukoi/YMMV


 * Alternate Character Interpretation: Some people have wondered whether or not Chiaki is deliberately playing the heartstrings of both Hatori and Yanase. Is he truly Oblivious to Love and doesn't mean to hurt their feelings or is that a front and he secretly yearns to make things difficult for both of them sending them mixed messages and then trampling on their hearts. Of course this comes up due to Chiaki's Base Breaker status.
 * Hatori gets this too mainly due to his Base Breaker status. Does he truly love Chiaki for who he is or is he want Chiaki just to rub into Yanase's face. Chiaki certainly thought this in episode 5.
 * And the Fandom Rejoiced: At least for those who cannot read the light novels, by adding the third couple (Hatori and Chiaki) to appear in the anime.
 * Base Breaker: Hatori gets a lot of flak. He's either the perfect candidate for Chiaki because of how he takes care of him and known him for twenty years or is hated because he's a possessive seme that will use force to hurt Chiaki and Yanase.  Same thing applies to Chiaki though. He's either the cutest Uke ever or the dumbest Uke that needs to see that's he's hurting both of his friends because of his idiotic nature.
 * The Hatori/Chiaki pairing in general is this. You either consider them the sweetest couple ever or you see a rather depressing relationship forming that is not sweet but rather disturbing especially if you read the novel.
 * Deconstruction: The love triangle between Hatori/Chiaki/Yanase can be seen as this especially considering the circumstance and how the characters react. Normally in a love triangle one person cannot choose between the other two and one person tends to give up for the Official Couple to be happy. However,
 * Draco in Leather Pants: While definitely not a villain, the fans that defend Hatori for his actions (in the novel concerning ) being justified in the since that he needed to do this in order to get Chiaki to realize that he had feelings for him. You can see how everything is divided.
 * Ensemble Darkhorse: Yuu Yanase is generally more liked than Hatori or Chiaki in terms of the love triangle. Despite being the character on the short end of the stick, he stands out a lot due to how his personality is different from what Nakamura usually writes. His voice actor and personality is very similar to a certain Troll from another anime helps his case.
 * Fan-Preferred Couple: A more minor example in that some people would prefer Chiaki with Yanase than Hatori.
 * Idiosyncratic Ship Naming: Unlike Junjou Romantica, the pairings aren't named by the author. The fandom makes up names for them nonetheless.
 * Nostalgia: Takano and Onodera
 * Domestica: Hatori and Yoshino
 * Erotica: Kisa and Yukina
 * Trifecta: Yokozawa and Kirishima
 * Idiot Plot: Episode 16 is regarded as one given that it focuses on Domestica. So Hatori cancels a date with Chiaki to meet up with his ex-girlfriend about rooms for two people. Chiaki ends up assuming that Hatori is cheating on him again (as he already assumed this in episode 6 when they first started dating), and what does he do? He goes complain to Yanase about Hatori "cheating" on him when in the last episode, Yanase has made it clear to Chiaki that he's in love with him and wants to be more than friends. While things don't end well for Yanase (and he's not really at fault in this episode), Yanase's  could have been avoided if...
 * a. Chiaki asked Hatori why he cancelled the date instead of assuming he's cheating on him. (To be fair, Hatori's ex was being too familiar with him and Hatori didn't explain her actions nor did Chiaki bring it up).
 * b. Hatori just told Chiaki what he was planning instead of keeping it a secret.
 * Hate Dumb: Some people bash Kisa because he breaks the stereotype Uke. Instead of him being Tsundere or innocent, he's very cynical and sleeps around, which apparently is a huge no-no for an Uke.
 * Internet Backdraft: Do not mention the Hatori/Chiaki pairing online and your opinion about  in the novel if you wish to save your heart from being broken.
 * Jerkass Woobie: Takano because  Naturally, he ends up being a huge jerk when he finally recovers but once the audience (and Ritsu) finds out about his past, you will feel sorry for him.
 * Yokozawa too would be in this category
 * Ritsu too would be in this category as the misfortunes he has is caused by him being in denial. Also  However, we know that Ritsu also has moments   He also doesn't get any respect from his worker and Yokozawa constantly harasses him to stay away from Takano when all he wants to do is get his life back together.
 * And of course Kisa. It's easy to feel sorry for him however, he causes most of the problems in the relationship with Yukina because of his pessimistic personality. However given his age and how he's given up on life (in terms of finding happiness because he feels like he's behind in everything), you can't help but pity him. Luckily, someone like Yukina can pull him out of his depression.
 * Mind Game Ship: Takano and Onodera in high school. In the last episode of the anime, Takano notes that he started to go out with Onodera...to crush his illusions.
 * Moral Event Horizon: To a lot of people, Hatori crosses the line when he  The anime was nice enough to tone it down but said fans aren't going to let what happened in the novel slide and it implies it in the anime as well. Being a Karma Houdini and   does not help his case in trying to redeem himself.
 * Never Live It Down: Hatori gets a lot of flak from people  The fact that the scene is never mentioned again pisses a lot of people off.
 * Chiaki may not be the sharpest tool in the shed but he's not retarded as you see people peg him to be. He's Oblivious to Love and has many dumb moments but people only talk about the dumb moments and not the moments where he actually stands up for himself and makes smart comments.
 * His insensitive nature is also another thing that people mention. Then again  will leave a negative impression on his character despite Chiaki wanting the best for his friend (at least at the beginning before the drama happened).
 * The Scrappy: Chiaki is not well liked in the fandom at all for his stupidity and his insensitive nature that contributed to Ensemble Darkhorse Yuu's.
 * Ship-to-Ship Combat: Hatori/Chiaki vs. Yanase/Chiaki. Take your pick and prepare for battle.
 * Tear Jerker: Episode 16. That is all.
 * Too Dumb to Live: Chiaki...Chiaki...Chiaki!!!!
 * Unfortunate Implications: The Hatori/Chiaki pairing gets this. Basically the summary of the pairing is that if your childhood friend is as dense as a rock and your rival might get to him first, the only thing you can do  He'll love you in the end and you'll hook up. That...leaves a bitter taste in the viewers mouth...
 * Another one that adds to the above that makes a lot of people feel bitter. So basically Hatori can  but Yanase can't even   To sum it all up, Hatori gets away with his actions because he's paired up with Chiaki but Yanase is treated like the villain for the opposite reason.
 * Wangst: Kisa seems to do this a lot especially in episode 20 where the entire episode is him debating whether or not Yukina really loves him or not, but given his personality, it's natural that he would be depressed.
 * The Woobie: One cannot help but feel sorry for Yanase especially given these situations.  By the end of episode 16
 * Chiaki would also be one if only because he's so oblivious and innocent compared to the other characters.
