I think you prefer school dramas with cute romance? So maybe check out:

  • Shut up flower boy band - very cute romance and more awesome bromance
  • Ma Boy - just unfreakin adorable
  • Revenge Note - though sadly it is not fully subbed
  • Puberty Medley - one udnerrated drama
  • Kingyo club - japanese drama that is more on the melodramtic side but the main couple is just adorable
  • Queen of the ring - MBC drama special
  • Be positive - web drama
  • Black devil and white prince - japanese drama that is a little funny and cute but sometimes irritating cause they guy is a jerk
  • Biscuit teacher and star candy - just a little heads up, this one has a teach student romance but still a good drama
  • Flower boy ramyun shop - not all scenes are school scenes, majority is actually in the 'store

Other school dramas that is not really too focused on romance:

  • Final Game - college
  • boy Next door
  • page turner
  • Jungle Fish 2
  • twenty again
  • Wuri's s House
  • Legendary shuttle
