Are there any VNs where you can romance the teacher? Also, student & teacher thread.
One of the seven couples in Okujou no Yurirei-san is about a girl in love with her (diminutive) teacher.
In Flowers Natsu-hen there's an ending where the protagonist falls in love with her teacher, but she gets rejected.
There's a few where a teacher has at least a sex scene with the protagonist:
Seisai no Resonance
Class Zenin Maji de Yuri
Yuri no Hana Renai Jijou
Yuri no Hana Gakuen Ryou
SonoHana has a teacher as one of the protagonists.
