VOL 1.
So the MC went to a special elementary school and on middle school he was an outcast but there he met Hana who protected him. Now on highschool they are still the same and walk home together, the MC goes to pick her up at her classroom, but accidentally hear Hana and her Friends talking, she was asked if she was dating the MC Todou to what she responded no he is just a convenient chore boy, Todou knocks on the door and Hana nervously ask if he heard them and replies that he didn't, then she gives him a love letter but doesn't say for who is it so he assumes its for the guy she said she liked not before doing the [Reset] Thing to delete every emotion associated with Hana
The [Reset] thing is an actual ability, i thought it was just autism but the MC can actually delete his emotions or memories towards someone.
The next dayThe class rep Michiba aproaces the MC, they spent a lot of time together while the MC helps her Study, she asks him out to a karaoke only the 2, MC declines, she gets a bit angry and invites him to karaoke but with the whole group, when the day arrives, she made the MC arrive 2 hours earlier and gave him the wrong address, after getting the correct address he is given the wrong room number too. Briefly but at the lounge area he sees his coworker Tanaka. He finally finds them but they mock him and say it was a harmless prank, the mc goes away and does the Reset thing again and stops their study sessions
After that we learn about Tanaka, a blonde gyaru who assist the same school but is in a special classroom and is a co worker to the MC, they just talk about how they met, pretty much MC is trying to work part time to learn how to socialize and she opened up to him and helped him socialize and adviced to stop using Reset and the MC tries to.
Next day at the classroom, the childhood friend Hana arrives crying asking why did he deliver the love letter to someone else, it was for him, she had to tell the guy it was a misunderstanding and asked why was he avoiding her, he tells her they dont have anything to do with each other and she realizes he used that Reset thing again with her and goes away pale and sniffling.
Another Girl, Another Reset, turns out the MC is actually a pro athlete because all he does is exercise or study, so he is friend and teacher to a kouhai called Sasami he met on his morning jogs, they meet at school one day and talk, after a bit the leader of the track team appears and belittles Todou because he likes Hana and is jealous, Sasami joins in the ridicule to suck up to him and calls Todou a Stalker along many other things, Todou does his Reset thing and forgets her. Oh, he also beats him on a race with just leather shoes. He also stops meeting her on their jogs
Because he destroyed his shoes running he goes to buy new ones and meets Hime, someone who knows him but he does not remember prob because of a Reset. He also ends up fighting a profesional boxer and knocking tf out of him.
He finds Hana walking to school and Tanaka pushes him forward to talk to her as most knew they had fought, after a bit of conversation the MC started realizing that maybe forgetting and resetting all feelings and memories you had with your only friend of years might've been a bit hasty and regrets it but hana bitterly sad agrees to start from 0 again as friends muttering that she will never give up.
The MC tries to mover forward and actually makes 2 new friends in the same classroom, Hana then arrives and then the class Rep Michiba out of jealousy starts calling her a liar, then the MC tells Michiba they have nothing to do in common and she almost cries scared of how he acts towards her now.
Tanaka and MC have a sorta Date
Sasami the girl from the track team, tries to apologize to Todou from calling him a stalker weirdo, she says she did it because the school they attend is actually high prestige and she is poor so she has to suck up to superiors, Todou says they have nothing in common and no association she goes away crying.
Todou asked Tanaka out since a while its obvious he likes her. Hana and Todou do a rehearsal date so that he is prepared, in the middle of it Hana is harassed by 2 frenchies speaking with a southern french accent (they specify on the southern for some reason) the MC goes to defend her and he too can speak french... with a southern accent lmao.
On a group activity nobody picks the MC, so Michiba says that she will do him the favour, he gets angry and tells the class he is leaving to another class, he was offered the special class a while ago and decided to accept, Michiba starts crying because she likes him.
The date with the Gyaru Gal Tanaka finally came and plan is for Todou to confess at the end. They go to a pet cafe, movie, a karaoke and near the end before MC tries to confess, Tanaka tells Todou he should pursuit Hana and to not have romantic feelings towards her because she doesn't reciprocate and she goes away crying, Hime then appears and tells him to go after her, which he does and yells he loves her, but Tanaka has been crying she fails to see truck-kun, the MC is too far away but then it turns out the Reset thing is an ability and he uses Limit another ability that lets him be super human at the cost of losing memories, so she saves her but forgets everything about her except the feeling he loves her.
At the end they sit on a bench, MC all bruised up asked secretly asked Hana who Tanaka is and because it was documented he gets the whole situation, Tanaka still tries to convince him to pursuit Hana and apologizes for monopolizing him, he doesn't tell her he lost his memories but he says he loves her but her guilt of stealing Todou from Hana doesn't go away, so after a bit, Todou decides if his feeling are whats causing her suffering he will reset again so they also start from 0, and thats where it ends.
If i compare it to other Osananajimi my childhood friend betrayed me whatever stories with ragebait titles i would say this isnt as bad, the plot actually moved forward.
Slight Spoiler for Volume 2
Turns out the MC might not have autism and is just a super human with conflicted emotions, at the start of Vol 2 they present Eris who is kinda like the mother or rather owner of Todou, turns out he was sold by his parents to Eris, a researcher, and that Special Elementary School? you thought it was special ed? nope xD its an actual militar research base for highly gifted kids, and other people can use the Reset very obvious Classroom of the elite stuff.
Something funny is that he says he dislikes southern france, the reason why is because as a kid he went on a mission to rescue a girl and failed lmao what.
