isn't the trauma only like...3-4 years ago??? it's not that long ago guys geez. and, it's not like she's ever dated since then and emotional maturity dating-wise isnt just going to appear out of nowhere.
also, trauma when youre young hits the hardest, she probably got it when she was 13-15, and right now is she even 19 (the age of adulthood in korea)? you guys have strangely high standards for young adults.
back to the chapter, sunbae is absolutely amazing and i also adore his new friends.
