Completely agree everyone is acting dense as if, if they were not in Doug’s pov 90% of the time they would understand why juheon would not want to be in a relationship with someone he holds resentment for regardless of if dohu was his first love, he doesn’t owe dohu anything especially since they broke up .
Exactly this! His whole life he was used by everyone, especially his family, and finally opened up for someone, was betrayed again! It leaves a huge trauma! Of course he loves Duha, this is why he's so damn conflicted, and for sure there is not only that betrayal part, there is much more regarding his family why he's pushing Duha away!
From the other hand we have Duha who understood his feelings through those 4 years and wants to fight for his love!
They both went through a lot, but you can see that they truly love each other...
They need to work on that and heal together, as none of them is without a fault here, but definitely Juheon's POV, especially form past 4 years will show more

the amount of people invalidating juheon's feelings is insane. i get you guys think it's not that deep but for someone who carried trauma for being used his whole life to love someone on the foundation of trust only for it to be a lie— the love, hate, doubt + family issues unfortunately is that deep.
