But to answer your question, i guess you could say he got one. Right before graduation and berreo entrance exams, Jun and Yohan make up. Jun only allowed this since he didn’t want to deal with bullying for the rest of the year. After entrance exams, Juns ends up dumping Yohan and blocks his number. This causes Yohan to spiral. Yohans bugs everyone about Jun, and one night Yohan gets drunk and ends up infront if Juns home. Jun tells him to get tf out before he calls the cops.
Graduation comes around and Jun goes. When he arrives at the ceremony, he locks eye with Yohan. June dashes and runs into an empty classroom. Yohan gets in and ends up on the floor sobbing and hugging Juns feet. Jun in a moment of feeling pity, kisses Yohan.
Jun leaves for the states after graduation for winter break. Once it’s time for college, he comes back and he ended up signing up for a dorm. His roommate hasn’t moved in yet so he thinks he doesn’t have one. After classes, he’s at his dorm debating if he should get dinner. When he decides to go, right when he opens the door Yohan appears right there as well. Turns out Yohan is his roommate. Jun thinks Yohan pulled some strings but it really was just coincidence. Jun notes that Yohan is more docile and obedient. Yohan says that he won’t act as he did before. Even tells Jin that he doesn’t believe in god anymore.
Some time later, Jun runs into an old classmate. To not spoil to much since i don’t know if you want to know; Jun, Yohan, and this classmate has a small incident. The classmate is really upset with Jun regarding said incident, and tells him if he drinks out of the soju bottle he’ll forgive him. Jun instinctively knows there something wrong, so the classmate just goes for the kill and tries to spill it on Jun. Yohan comes out form idk where and takes the blow. Turns out the soju was actually acid and burns Yohan shoulder, if you remember the scar from the extra wink wink.
At the hospital. Yohan ends up getting surgeries and skin grafts. Yohan tells Jun that he doesn’t care about god and he’s going to start believing in Jun instead since God has never done anything for him. Jun doesn’t believe it, so Yohan gets in his feet and starts slowly going up from there. And that’s where the main story ends.
I spoiled a small part of the novel, so that you can form your own thoughts on rather this is a redemption arc, chasing arc, etc. Also so that you can make up your own mind whether this is a ‘good’ or ‘bad’ ending.

Does Yohan get a character development or chasing arc shit? does anyone knows who Kangjun will end up with? I hope it’s noone of them cause wdym Yohan is a literally a psycho
