Manhwa Recommendations

Error Detected is the most similar one that comes to mind. Though when it comes to other highschool romances I can still recommend Wild Beast Warning though it’s definitely less angsty.

Autobahn Romance has a very cute highschool-arc at the start, so if that’s enough for you, I’d also really recommend that one.

If you ask for my recommendation looking away from the highschool genre, which are green, I’d recommend:

Little Mushroom(Toe, curling setting and brilliant relationship. You’ll get Angst too.), Turning (Historical, but brilliant worldbuilding), I Want to Be a Big Baddie (Very cute, but don’t underestimate the plot) and The Hunters Gonna Lay Low (great characters, great relationship).

Except the first one they all have a rather happy atmosphere though… so to get more into the angsty feelings of lost in clouds, I’d recommend:

“Murderous Lewellyn‘s candlelit dinner”. Though it’s not on this site yet, the angst and the relationship won’t disappoint.

If you’re fine with more fantasy ones, I could list some more, but I don’t read that much highschool romance, so… sorry if I couldn’t help you.
