i read the whole novel a while ago and i mean the redemption arc was short for my taste, from here on i will make spoilers so i advise you:
So rn jun is trying to survive high school with trying to not anger yohan but still taking his distance, so he will be kinda like an outcast with a little of an annoying yohan on the side.Its important to know that slowly jun will stop caring about others opinion (that doesnt affect him, like he will be a hypocritical but for convenience like he will try to make an alliance with some classmates to try to survive the tough ambient -if you were a nerd/outcast in hs you know its important to atleast to not draw the attention and do an effort to blend in so the other people at least wont bully you)
The actual redemption arc goes when jun finishes school and dgaf about anything no more and wont go to his own graduation to this point he slowly try to distance himself from yohan (and in the novel from what i remember said that yohan seemed hurt and angry) and the actual suffering from yohan comes when jun cuts contact with him before going to college and when they encounter by entirely coincidence as roomates as newcomers on college, jun tried to avoid as a pest yohan and yohan actually gets the clue and stops trying to chase him, so he suffers, he still longs him bcs yk, but this arc was short af bcs it ends when yohan idr why was near jun and jums in to save him from an acid attack made by the crazy ass mf that jun's mother got expelled.
If you want to know more let me know, i really liked the novel but the satisfaction i got from the chaser arc was not enough imo, yohan was a cutie after tho so still worth it. And dont trust this spoiler completely bcs i remember the majority but not the details and the manwha author can still change things as though they are making a great job in conserving the majority of the og script from the novel (most of manwhas adapting korean novels mess up tho and xhange entire lines of plot lmao).

Y can’t Jun be more mean to ML? Bro needs a LOT of grovelling than this man Idc pls spoil me, am I wasting my time?
