Ml thinks the mc looks down on him (let’s be honest, he kinda does lol) and he thinks the mc is using him (kinda true too lol). Also with the whole dinner incident, he’s mad at mc right now. Basically he’s throwing a tantrum expecting mc to be the one to bow his head and give in first.
Also there are a lot of novel spoilers in the comments, you can look for them if you’re curious. The angst phase is now starting

i’m pretty much lost with the plot, can someone explain why yohan is giving kangjun the cold shoulder? im sorry!! and i don’t mind spoilers from the novel ヾ(❀╹◡╹)ノ~
