* Yuu's friendship with Tomoko gives much needed spots of light in her universe.
** In chapter 3 of the manga/episode 2 of the anime when Tomoko noticed that Yuu was upset she took her to the arcade where they used to hang out in their middle-school years to cheer her up. And while Tomoko at first lied to Yuu about enjoying her time in high school, when she realized that something was still bothering Yuu she blurted out the truth and tried to raise Yuu's spirits. What happened immediately afterwards kind of ruined the moment; however, the scene still shows that Tomoko doesn't just think of Yuu as a LustObject but actually cares about her as a person.
** In chapter 64 Tomoko again shows that she actually cares about Yuu. In that chapter Yuu is upset that she can't have fun with Tomoko and Kotomi on a beach because it is closed, and eventually starts to cry. Tomoko then apologizes to Yuu for picking this particular beach, and she and Kotomi promise to take Yuu to a better beach next time. They keep their promise in the very next chapter. Chapter 65 also has a FriendshipMoment between Kotomi and Yuu, as Kotomi tells Yuu that without her she and Tomoko would probably just waste their summer break away and have no fun; in response Yuu assures Kotomi that she had a lot of fun hanging out with Kotomi and Tomoko.
* Although Tomoko feels embarassingly pitied by it, the way her little cousin Kii-chan cares about her is rather sweet.
* The cicada shells.
** Really, any scene between young Tomoko and Tomoki... which retroactively becomes a TearJerker considering their relationship now.
* In an odd and strange way, her rivalry with Komiyama. They are so shy, that having someone to fight against feels like an improvement.
* The female StudentCouncilPresident noticing her all alone during the school's cultural festival and getting into a mascot costume to hug her.
* In chapter 42 the same StudentCouncilPresident notices that Tomoko's teacher unwittingly embarrasses Tomoko in public by questioning her on whether she had made any friends. She then comes to Tomoko's aid by declaring herself to be her friend.
* Her dad, finding her sleeping in a [[spoiler: compromising scene, gently puts her in bed, without waking her up, and tidies up her room.]]
* In the spin-off, Yuu had suddenly achieved popularity when going to school without her glasses and braids. The next day, she puts them back because she found it difficult talking to her true friends with so much attention drawn to her.
* The rare occasions when Tomoko manages to talk to someone without embarrassing herself (such as in chapters 37 or 44), and the fact that during the second year of high school she actually makes an acquaintance in her class, are themselves heartwarming, but especially heartwarming are the implications of all of this: that Tomoko does actually make some progress at socializing, even if only at a glacial pace.
* Episode 6 of the anime has Tomoko trying and failing as only she can to get someone to go watch fireworks with her. Finally, at the end of the episode, she just goes to a desolate roof she used to hang out on...only to discover some middle school boys were planning on hanging out there. Tomoko is about to leave, but then timidly asks if she can stay and hang out with them. The boys say they don't really mind so she stays to see the fireworks...[[spoiler: and to peep into the rooms of the next door love hotel, which is what the boys came there to do]]. Something about the boys calling her "Onee-sama" is heartwarming, as she bonds with them [[spoiler: over being Peeping Toms]]
* When Tomoko has her umbrella ruined and is stuck under a roofed waiting area with two guys her age, she proceeds to embarrass herself in front of them [[SelfFulfillingProphecy when she tries (and fails) to not make a fool out of herself]]. Notably, the guys don't mock her, and the friendlier of the two even comes back to hand her a new umbrella (which he bought with his own money). He leaves it by her side when he finds that she's fallen asleep. Too bad Tomoko never really realizes that someone did an unmotivated act of kindness for her.
** If it is any consolation, she does meet up with one of the guys in a later episode, who mentions the above. Too bad she tried reading too much into it, and how she used him to try to impress her cousin.
* In episode 12, Tomoko tries a new tactic of trying to get the students to talk about her by doing stuff the same way the StudentCouncilPresident does. However, her first attempt fails miserably, when she squishes a roach in the class, and the students are disgusted by it rather than proud of her. She then tries to approach the president and talk to her casually, but a gust of wind provides Tomoko with a PantyShot of the president, embarrassing her to the point of running away before she could utter a word. Two students then approach from the other side of the walkway, and ask the president who that girl running away was. She tells them a little about Tomoko, saying she's a cute girl who she'll need to keep an eye on.
** At the end of the episode, we get [[BookEnds another scene like the first scene]], where Tomoko is looking at the definition of an Unpopular Girl again...except this time [[spoiler: she ends up laughing at the term and says it doesn't matter]], one can interpret this as her finally finding confidence in herself.
* Chapter 57: [[spoiler: Tomoko and Komiyama haven't noticed, but Yuu and the readers saw something...]]
* The end of Episode 5, when her mother calls her phone and tells Tomoko to come home so they can eat sukiyaki. It reminds her of the warmth a family home can give, especially comforting when she feels obviously lost and out of place in the red light district.
* Chapter 62: [[spoiler: Tomoko's joy after learning how to ride a bike.]]
* Chapter 68 had Tomoko have a pretty good day at school. In fact, all her inner monologue about how feudal era girls could have spent their time (watching [[YaoiFangirl other lords get it on with each other]]) led her to a passing grade on a pop quiz.
* During the class trip plot, Tomoko seems to have gotten a lot better at just talking to people normally, even if she still does or says awkward things. Then, there was that moment in chapter 73, when Tomoko's classmate knows Tomoko is in the bathroom and she is unable to come out because she left her pants in the other room, and she helps a sister out by throwing her pants to her. And in chapter 74, Tomoko is able to harass the "delinquent" girl and ask another girl in her group to save her from said delinquent when she gets annoyed. The latter girl's internal dialog reveals that after getting to know her, she doesn't consider Tomoko a weirdo or a loser. [[CrowningMomentOfFunny Just an idiot.]]
* [[spoiler: In the final chapter of the spin-off, Yuu talks about how her daily life with Tomoko and Komiyama is precious to her and that she wants it to continue forever. In the last panel, after the three of them started to see each other again in Watamote, we see Yuu's happiness in being together with her friends again.]]
* Chapter 98, Where [[spoiler: Yoshida, despite denying that she and tomoko are friends, gets wet protecting tomoko from the rain]]
* Chapter 102 had Tomoko and Tomoki watch ''[[LightNovel/HaruhiSuzumiya The Disappearance of Haruhi Suzumiya]]'' together while their mom was out. We not only get an adorable flashback from when they did the same as children, but we get Tomoko actually acting like a normal older sister and taking a walk with him.
* In the seventh special chapter, Tomoko finally gets to celebrate Christmas in the company of friends, eating cake, singing carols, and exchanging gifts. Though she had to deal with plenty of hilarious humiliations that day, like being forced to sing karaoke for an hour at Yuu's request, she's happy that she managed to celebrate Christmas properly for the first time in her life.
* In chapter 112 Yuri [[spoiler:acknowledges Tomoko as a friend for the first time]] while they are making Valentine's Day chocolates.
* Yoshida of all people gets one in the second part of chapter 115 [[spoiler:when she drags hesitating Tomoko and makes her say proper farewell to the graduating StudentCouncilPresident.]] Also [[spoiler:said StudentCouncilPresident gives Tomoko a hug again]].
** While 115 ends on a TearJerker note with Tomoko getting emotional over [[spoiler:her parting with Megumi]], it's heartwarming in how it shows Yuri and Mako are there to give her support as they all walk home together. YouAreNotAlone anymore, Tomoko.
* Chapter 119 has Tomoko dithering on whether or not to go to a class party, but Yuri talks her into going and at least two other classmates ask if she will go. It ends with Tomoko calling her mom to tell her where she was at, for Tomoko to do something as normal as going to a party this is a big indicator of how much her school life has changed.
* The entirety of chapter 120 is heartwarming, as it shows how much progress Tomoko had made in socializing since the beginning of the story. The crowning moment of heartwarming, however, is the reveal why Yuri convinced Tomoko and Yoshida to go to the class farewell party: [[spoiler:as she didn't know whether they would end up in the same class during their final year of high school, she wanted to spend a bit more time with them.]] Eventually, as Yuri leaves before the rest of the class goes to a karaoke bar for afterparty [[spoiler:Mako, then Yoshida, and finally Tomoko join her. The chapter ends with Yuri [[FriendshipMoment asking the three of them to hang out together a bit longer]].]]
* Yuri's [[NotSoStoic joy]] in chapter 122 when she finds out [[spoiler:Mako, Tomoko and Yoshida will be in the same class as her during their third year of high school]].
