Horimiya (2021)

Both MLs are shy and withdrawn, FLs are more outgoing. Both are set in school and one of the characters' family owns a dessert shop.

They're both short dramas about high schoolers with different personalities and social lives bonding and forming strong friendships. Both dramas are wholesome and don't rely on clichés to carry their plots.

Although admired at school for her amiability and academic prowess, high school student Kyouko Hori has been hiding another side of her. With her parents often away from home due to work, Hori has to look after her younger brother and do the housework, leaving no chance to socialize away from school.

Meanwhile, Izumi Miyamura is seen as a brooding, glasses-wearing otaku. However, in reality, he is a gentle person inept at studying. Furthermore, he has nine piercings hidden behind his long hair and a tattoo along his back and left shoulder.

By sheer chance, Hori and Miyamura cross paths outside of school—neither looking as the other expects. These seemingly polar opposites become friends, sharing with each other a side they have never shown to anyone else.

Similar vibes, school setting, lovely storyline

Fifteen-year-old Sei Saotome is the type of person who tends to fail at the most crucial times. After nearly becoming a high school drop-out, she enrolls into a school that is overambitious for her. There she meets the bold and popular Taiyou Udagawa; and the dreamy and stars obsessed, Mizuki Ootaka. After being asked by Mizuki to join the two guys in the Astronomy Club, it turns out high school life isn't as bad as she had expected.

Miyu and Shuya are high school students. They have dated for 2 years. Miyu and Shuya have a promise that no matter what, they will watch a movie together on the first day of each new month. When Miyu and Shuya are on their way to the movie theater, Shuya suddenly cancels their date. Shuya seems like he is hiding something and he acts nervous. Later, Miyu goes to the place where she is supposed to meet Shuya, but she witnesses Shuya getting into a car accident. She panics, but when she wakes up she finds herself on the morning of the accident. Miyu keeps waking up on the day when Shuya got into an accident.

Both are high school where the male leads seem to be unapproachable due to their respective appearances, yet they are very gentle as a person.

Rikako of the twelfth grade repeated play at night with her close Miki every day. One day she meets (and becomes infatuated with) Tomoaki Fujii, who's rumoured to be the Don Juan of her school and even impregnated a girl before getting an abortion in his father's hospital. This doesn't bother Rikako one bit, as she too sleeps around. But Tomoaki, knowing Rikako's true intentions, shoves her aside. Rikako later finds out that Tomoaki is quitting school to move to Okinawa, and she finally attempts to understand him. From then on, they form a close bond.

Both dramas have an extrovert FL and a very withdrawn ML who everyone thinks is odd until his relationship with the FL brings him out of his shell. Both are sweet dramas with no love rivals or breakups for the main couple.

It's Shouko Komi's first day at the prestigious Itan Private High School, and she has already risen to the status of the school's Madonna. With long black hair and a tall, graceful appearance, she captures the attention of anyone who comes across her. There's just one problem though—despite her popularity, Shouko is terrible at communicating with others.

Hitohito Tadano is your average high school boy. With his life motto of "read the situation and make sure to stay away from trouble," he quickly finds that sitting next to Shouko has made him the enemy of everyone in his class! One day, knocked out by accident, Hitohito later wakes up to the sound of Shouko's "meow." He lies that he heard nothing, causing Shouko to run away. But before she can escape, Hitohito surmises that Shouko is not able to talk to others easily—in fact, she has never been able to make a single friend. Hitohito resolves to help Shouko with her goal of making one hundred friends so that she can overcome her communication disorder.
