the mc is a side character in his own story lol

Feels more like there are two MCs to me. I’ll just rely on the cover for this conclusion

Cover means nothing in comparison to the difference in screen time and importance to the story they have through the 90+ chapters currently out

Still, the feeling remains: we basically have 2 MCs. Everything about Changsoo is typically what you give your main character while half the stuff about Bahkeo is what you give to the MC’s best friend.
