Let's start this list with Doukyuusei – Classmates! Hikaru Kusakabe is a popular teenage guitar player; Rihito Sajou is an earnest honor student. These two boys are literally on the opposite sides, but due to something happened during the preparation for the chorus festival, they end up practicing together. One thing leads to the other, and eventually they fall madly in love with each other. Kusakabe and Sajou will face a lot of hardships trying to tear them apart, but love will triumph!

Sekaiichi Hatsukoi: Valentine-hen and Doukyuusei are both two masterpieces of the BL world. Both these movies share the main theme of a difficult romance between two boys; Kusakabe and Sajou are younger than the characters in Sekaiichi Hatsukoi, yet both these shows share the same good vibes, and deal with delicate themes lightheartedly. Doukyuusei is less comedic, but it's still enjoyable as Sekaiichi Hatsukoi: Valentine-hen!

Takao Akizuki is a 15-year-old boy, and an aspiring shoemaker. On a rainy morning, when he decided to skip classes, and go to a beautiful garden to draw some shoes sketches, he has a fated meeting with Yukari Yukino. The beautiful and mysterious 27-year-old woman catches Takao's attention, so Takao offers to make her new shoes. Without even realizing it, those meetings become each other's salvation from their personal struggles, and inner demons. When the rainy season comes to an end, though, what will become of their somewhat weird relationship?

Kotonoha no Niwa, with its settings, soundtracks, and amazing visuals, is one of the best movies created by Makoto Shinkai. Even though it's not a BL, this romance still shares plenty with Sekaiichi Hatsukoi: Valentine-hen. Kotonoha no Niwa speaks of an innocent love between two persons with a huge age gap. Like Sekaiichi Hatsukoi, Kotonoha no Niwa is a slice of life with a lighthearted atmosphere, which is still able to melt your hearts. Give it a try if you crave for a romance as sweet as those in Sekaiichi Hatsukoi: Valentine-hen.

Shima Kawauchi is a lonely teenager whose life is turned upside down when one night, by mistake, he drops his grandfather's picture in the ocean. Unable to swim, he still jumps in the water to try to get it back. When he is about to drown in the water, Shima is quickly saved by a strange individual: he is a merman, and his name is Isaki. After moving in with Shima, Isaki begins to show his immature and childish behaviors, yet, on the other hand, the two of them manage to create a deep bond, and eventually a deeper feeling develops...

Both Sekaiichi Hatsukoi: Valentine-hen and Kono Danshi, Ningyo Hiroimashita are short movies, with shounen-ai/BL elements. Shima is very similar to Kisa Shouta in Sekaiichi Hatsukoi, what with their being shy, and unable to open up to people, at least before meeting their counterparts – Isaki and Yukina. Pick Kono Danshi, Ningyo Hiroimashita if you wish to watch something similar to Sekaiichi Hatsukoi, but with a supernatural element!

Kurumi is a young woman who was struck by a tragedy: she lost her will to live after losing her boyfriend Hal, who died in an airplane accident. Kurumi became unwilling to deal with her loss, so she holes herself up in a gloomy state, unable to eat, smile, or even cry. The situation changes when her grandfather requests the humanoid robot Q01 to take on the appearance of Hal, and help Kurumi recover. In the beginning, the robot's efforts seem pointless, but then gradually Kurumi begins to open up and, possibly, overcome her depression.

Hal is way more dramatic than Sekaiichi Hatsukoi: Valentine-hen. Yet, both these movies' main theme is love, faced in a lighthearted way. So, if you enjoyed Sekaiichi-Hatsukoi: Valentine-hen because of the romance, you'll find the same vibes in Hal, even if the drama is high and you'll probably need tissues by the end of the movie.

This story revolves around Natsuki Enomoto, and her love toward her childhood friend Yuu Setoguchi. One day, Natsuki finally mustered all her courage to confess to Yuu, but the awkward moment that followed right after, made her say that it was just a practice confession. Confused, Yuu promises to help Natsuki in her quest of love, but he is left dealing with his own feelings. In the meanwhile, another character enters the picture: Koyuki Ayase – Natsuki's classmate. Koyuki's goal is to win Natsuki's heart over!

Zutto Mae Kara Suki Deshita may be considered almost like the shoujo version of Sekaiichi Hatsukoi: Valentine-hen. In fact, Natsuki will face the same awkward moments that each character in Sekaiichi Hatsukoi faced. For example, Natsuki's blushing face will remind you of Onodera's blushing face; Yuu's inner struggles will remind you of Takano's inner struggles; tender, and innocent moments between Yuu and Natsuki will remind you of Yukina and Kisa's tender moments. With the same amount of comedy parts, as well, you are bound to like Zutto Mae Kara Suki Deshita!

This love story comes directly from Sekaiichi Hatsukoi universe, and it revolves around the couple made of Takafumi Yokozawa and Zen Kirishima. Kirishima is a single father, and the editor-in-chief of Japun. Yokozawa works in the sales department, and he is very serious about his work. When Yokozawa's heart was crushed into pieces by an unrequited love, these two men get closer and closer. Until a deeper feeling develops between the two, and both their lives change for the best.

Sekaiichi Hatsukoi: Valentine-hen was screened alongside with this movie; in fact, both Yokozawa and Kirishima are two of the protagonists. It may be pointless to say what these two movies share: they're both shounen-ai/BL stories, full of romance, and comedy. Basically, if you wish to see Yokozawa even more troubled than in Valentine-hen, and enjoy his reactions to whatever Kirishima does, this movie is what you're looking for! And since it's longer, the enjoyment multiplies.
