Rakthasat 311, Nithesat 224, and Sathapat 510 are part of the short story novel “University of Love” (มหา’ลัยมาหารัก) by JittiRain, they were originally released around 2015–2016, so it’s been quite a long time, there was never an ebook version, they were only published in physical format and the books are now out of print due to their age, but the 3 stories that are set to be adapted by gmmtv are included in this translation. Feel free to read.
