Yahari 4-koma demo Ore no Seishun Love Come wa Machigatteiru.

こうして彼らのまちがった青春が始まる。

After writing a less than flattering essay about his high school life, Hachiman is forced to join a very unique club with only one member.

きっと、誰しも等し並みに悩みを抱えている。

As Hachiman continues his narrative of his school life, tension rises in the room as Yui attempts to break away from her social group. If that wasn’t enough, the club has received a new request from a unique visitor.

たまにラブコメの神様はいいことをする。

Hachiman continues his solitary lifestyle by using his skills to ensure he is left alone during gym and lunch. His routine is broken by the appearance of Saika Tosuka, who has come to him with a request.

つまり、彼は友達が少ない。

Hachiman questions what it is like having a sister in real life means. While walking her to school she brings up the car accident he was in while saving a dog. At school, he is once again berated by Shizuka on his response to the “Career Observation Application survey”. When he finally makes it to the club room, a mysterious text sets off the clubs next request.

またしても、彼は元来た道へ引き返す。

Hachiman's younger sister, Hikigaya Komachi, was asked to give advice to a fellow classmate, Kawasaki Taishi. Apparently his sister had been acting strange. His older sister, Kawasaki Saki (though Hachiman wasn't aware of this), was in the same class as Hachiman and Yui, so the Service Club decided to help with the issue. They come up with various ways to try to dissuade Saki from her suspicious activities, but...

ようやく彼と彼女の始まりが終わる。

After their confirmation things are different between Hachiman and Yui, Hachiman revels that he was able to reset his relationship with Yui, while Yui stops attended club meetings. Shizuka informs them that they need to go on a recruitment drive and Yukino knows the perfect person.

ともあれ、夏休みなのに休めないのは何かおかしい。

Trying to rest during summer vacation, Shizuka constantly calls and text. Komachi breaks the cycle when she Hachiman agrees to take her to Chiba. But before they make it to the station…

いずれ彼ら彼女らは真実を知る。

Shizuka readies a bonfire and a “test of courage.” Later, Yui recognizes the limo that hit Hachiman.

三度、彼は元来た道へ引き返す。

Hachiman becomes restless as summer draws to an end. A Firework Festival opens the door for more teasing and many SNAFUs!

依然として彼らの距離は変わらずに、祭りはもうすぐカーニバる。

Yui notices a rift forming between Hachiman and Yukino. Hachiman is nominated to serve on the committee for the school’s upcoming cultural festival.

そして、それぞれの舞台の幕が上がり、祭りは最高にフェスティバっている。

Hachiman and Yui check on Yukino. Later, Hachiman shakes things up with the committee when he decides to alter their mindset.

こうして、彼と彼女と彼女の青春はまちがい続ける。

Soubu High's Cultural Festival continues and Hachiman is stuck carrying out his duty as a committee member by documenting the day's events on film.

だから、彼らの祭りは終わらない。

A mysterious request to helm the upcoming sports festival arrives. The group must band together to figure out a way to pull it off.
