Oh no nakyum's nightmare! It was his guilty conscience. He still doesn't know that inhun's has hidden agenda behind his back and that inhun is still special to him after all. And now that inhun's dead, he's still with seungho who everyones talking about who killed inhun (ofc he doubts seungho too cause everyone's talking abt it that's why he's going to ask o know the truth) and yeah that's why he's feeling guilty to inhun. But it's for sure that after seungho tell him the truth, he will believe him ofc it's because he loves him, that way his guilty conscience will fade away. huhu poor kyum in this chapter??
