I didn’t say it was not somehow related to incest, and I do think this timeline is before the other story considering the ML still thinks or treats YJ as his brother and not his brother’s lover.
Pseudo incest or not, what they are doing is not illegal. It’s a conflict morals. The older brother took YJ because he pities him while YJ don’t see the older brother as a brother in reality.
But if this bothers you too much that it triggers your anger, probably safer to skip this scene.
so, are the two brothers together now or does the other story happens sometime in the future?
