If you liked the Gakuen Heaven anime, the Anime-Planet community thinks you'd like:
Tachibana has recently quit his job at a high-class firm, and for unknown reasons, decides to open a bakery. His first employee is Ono, an extremely talented patissier who is also known as the 'Gay of demonic charm' - something that has caused him to lose his job countless times. Joining the crew also is Eiji - a retired champion boxer - who is hired on the spot as only a trainee purely because he is not Ono's 'type.' However, Chikage, the bumbling childhood friend and shadow of Tachibana, is exactly his type! Now, with the shop finally open, everyone seems to be filling their positions well; but one question remains: what were Tachibana's motives for opening the bakery, and does it have a link to his troubled and forgotten past?
Both of these anime seem to have some obvious connections; extremely slashable bishounens, a main character with a mysterious past, storylines along the lines of finding new friendships, etc. But even more than that the comedy is similar as well as how the story develops. If you like one then you'll definitely like the other.
During a much needed vacation in England, American cops Dee Laytner and Randy McClane find out that danger has found them yet again. Their hotel, it seems, is under investigation for a series of murders which cannot be solved, perplexing local authorities and visitors alike. Now, Dee's clever plans to take Randy's virginity must be stalled in lieu of the investigation, since hesitation might cost both of them their lives!
Both series are shounen ai and include all of the good things: bishounen (handsome guys) and romance. In both, a cute boy falls in love with a tall handsome guy (or the other way around) and you follow their difficult journey to be together. If you liked one of them, you'll surely like the other one as well.
Misaki Takahashi has little hope of getting into a university, so his older brother Takahiro's friend, Usami Akihiko, offers to tutor Misaki as a favor to Takahiro - for Usami is secretly in love with him. However, as time passes Misaki realizes that he has uncomfortable and budding feelings for Usami. Meanwhile, Hiroki is a man who can't get over an unrequited love with Usami in the past - and with the help of Nowaki, he may finally learn to love again. These couples and more experience the joys and sadness of love between men under the most unlikely conditions.
Gakuen Heaven and Junjou Romantica are yaoi romances set in a school environment. Plenty of humour and fluff dominate both titles. Gakuen Heaven, for all its innuendo, is considerably tame compared to more adult content in Junjou Romantica and both titles offer enough eye candy and comedy to share a common fanbase.
Upon trying to save a friend from bullies, Shibuya Yuuri finds his head in the unlikeliest of places -- the toilet. Like a flash, Yuuri is then inadvertently sucked in, transporting him somewhere else! In this unfamiliar world of flying skeletons and magic, he is informed by a group called the Mazoku that he is to be the next Maou -- ruler of the kingdom! With harrowing and embarassing situations ahead, can our hero swallow his pride and lead a war against the common people when he can't even tell the difference between a slap in the face and a marriage proposal?
Gakuen Heaven and Kyo Kara Maoh are both shounen ai-centered anime, both of which center heavily on relationships between the various characters. The romance and humor are also very similar, as both main characters (Yuuri in KKM and Keita in GH) are innocent, nice guys who are "thrown" into a different "world" than they are used to (literally in Yuuri's case). If you watched one and liked it, there's a good chance you would really enjoy the other!
High school life is good for Morifuji Shizuka. With good grades, popularity and a fair share of friends, he is not to be left wanting -- except for one thing. Although the all-important finals are around the corner, the one thing on Shizuka’s mind is his classmate, Ichitaro Sakura. But is this attraction real love, or simply something physical? And what will the innocent-minded Sakura think of another boy having feelings for him?
Shounen-ai in a school setting is the basic outline of both titles. Gakuen Heaven has lively artwork and develops a rather convoluted subplot along the way, while Lesson XX is rather bland in terms of artistic content and deals almost exclusively with romance. Both follow the first stages of a romantic relationship between two male characters, and lavish on dramatic moments.
