@veggklokken yeah she's her friend from the normal class. She doesn't know her and Ji-tae are living together but, just a couple chapters ago, she was suspicious of Maria walking with them to where they live.
im skipping a lot of chapters cuz its getting on my nerves for it to be so long and lots of unnecessary screen time or fillers. The plot's good but mc screen time for training is low that i dont even know if he is still the main character.
