This was Miyabi's backstory. She had a crush on her teacher. When she found out he was engaged, she pretended he had raped her and ruined his reputation as she spread the rumor over the school.

Mentioned in a flashback in Hanamaru Kindergarten. Anzu's mother got pregnant by her art teacher, married him, and dropped out of school. Generation Xerox takes effect, as Anzu has the same idea for Tsuchida, her kindergarten teacher. Sakura, Anzu's mother, approves of this. It's played off as a tremendous Precocious Crush, which is common with little girls and guy teachers in real life. It's never really stated whether Anzu's mom realizes this and counts the relationship as harmless (to encourage Anzu to develop feelings of love and friendship), or if she's actually serious about approving their marriage before she even turns 6.

Too bad "Alice" finds Kouya later, and sees in horror that he actually crossed the Despair Event Horizon and become a borderline Empty Shell.

In My Monster Secret, Sakurada (one of Those Three Guys) admits that he's got a crush on their teacher Akari, but doesn't feel he can confess until he can defeat her (they're both former delinquents, and Akari's responsible for Sakurada's mellowing out). All of Sakurada's friends become Shippers On Deck, not just because he's the nicest guy you could ever meet but because Akari's been freaking out about being single for a while and they want her to be happy.

The Negima! metaseries does it differently, in that the teacher is actually younger than the students... but it's deliberately set up to look like a Harem Series without actually being one.

Negi constantly worries about maintaining a normal student-teacher relationship with the girls, but it gets progressively difficult.

At the film's conclusion, it strongly implies that she still has feelings for him.
A running gag in The Prince of Tennis anime series is Reiji Shinjou's obsessive loyalty to his coach, the busty and gorgeous Aoi Hanamura, which borders on a Stalker with a Crush level. In the Atobe kara no Okurimono mini-movie, Reiji is constantly spouting ''... Sensei!!" at her while looking betrayed during a scene that parodies dating shows. Hanamura-sensei herself practically ogles and fangirls her own pupils when in really high spirits, both in the Jyousei and the Senbatsu arcs.
Salad Days: Honjou's in the school's news club. He frequently gets reprimanded by Mr. Miyagi for writing sensational garbage articles.

But before he could realizes his plan, a cute senpai named Ryouko Matsushima comes into the club room and tells him her experience when working under Mr. Miyagi. Her situation was comically similar: she also wrote bad articles, got scolded, then decided to write a libelous article about this scary looking guy who was rumored to be a thug. It turned out that this guy only looked scary, and because of his looks nobody believed him. It was so serious this time around, that instead of giving a comical knock on the head, Mr. Miyagi just straight up slapped her and gave her some serious reprimand about how irresponsible she was to accuse someone who couldn't defend himself of something horrible. The incident left such a deep impression in her that she started developing feeling for him and ended up marrying him. Her moving story sways Honjou so much, the next morning, even though he still gets punched by Mr. Miyagi for writing an article about "Mr. Miyagi (35) marrying his former student (23)", he still chooses to maintain journalistic integrity and just makes good, light-hearted fun of his teacher.
Played for dark laughs in Sayonara, Zetsubou-Sensei. The plot revolves around a suicidal teacher who accidentally wins the hearts of nearly all of his students, some more extremely devoted than others. Itoshiki himself rarely returns any of the feelings of his Harem ...until the end. What happened is that he had loved the First Girl, Fuura Kafuka, long ago and saw her die. Kafuka's organs had gone to the twelve girls (and one guy) in the class he teaches. Kafuka's able to possess them that way, and eventually, in his eyes, Itoshiki marries Kafuka. To outsiders, though, it looks like he married them all.

A Hentai/Romance manga called "Teacher and Student" by artist Fuuga revolves around the budding relationship between a student and his teacher when an eviction causes them to move in together. Interestingly, there's a good deal of focus on their own concerns about the relationship, as opposed to being worried about what others will think. Subverted in that by the end, she's resigned and is no longer his teacher. Many of the titles in the "Fuugaverse" are based around the same group of students/teachers, so this topic comes up a couple of times in various forms through his works.
In Tokyo Ghoul, Akira Mado reveals that her parents were such a couple. Kureo met Kasuka when she was one of his instructors at the Academy, and eventually married her after several failed proposals.
