yes! if you haven't read it yet “save me” its very good and a very similar thriller with nice plot twists but they do show a lot of bullying too. Another good thrillers are bastard, sweet home and uriah. Also Lookism isn't much of a thriller but deals with bullying, beauty standards and overcoming adversities in different ways (if you're interested).
Does anyone know some comics with a similar artsyle or as good as this? I cried so many times. Poor Hyung. I already had a feeling he was gonna die anyways ;-;
