Namjoon was no optimist unlike Hyeri. He was a realist.
He weighed in every possible outcome to a particular step before taking it and that was what led him to that place in the first place.
The fear of losing his lover, his soulmate, his Hyeri in this strange place was so big that the fact that Hyeri was so skilled and strong skipped his mind while he was calculating the pros and cons.
Without a doubt, he believed her. He trusted her with everything he had. Not just him, his family did too. Enough to let her in in all the family secrets and missions.
His trust on her was more than he had in himself, he had never seen anyone so brave as Hyeri.
From the moment he had laid his eyes on her, she had moved him beyond words. Suddenly, all the love songs and romantic poetry had started making sense to him and his preference in entertainment changed from action to romcoms.
