He fully understood the meaning and intent of following the brother to the bathroom; he knew they passed by 2 bathrooms already, he felt danger to the point of trembling just by the mere presence of the brother since his appearance so yeah why would he still follow the brother?
It all comes down to power, one glaring detail is this party was organized by his fiancé’s family. Since the start, the mc showed eagerness to please his adoptive father to the point of sabotaging his fiance. Why was the mc even engaged to the ml in the first place, because his adoptive father wanted the power of being connected to the organizer of this current party, so wouldn’t it conflict with what the mc has bet his life and body on if he made a scene and ruin that connection. The mc agreed to the marriage knowing full well he was being sold out by his adoptive family, following a dangerous individual to again please his adoptive family is still consistent with what he was from the beginning, nothing changed.
Really?? You've been given all the signs yet your survival instincts still told you to follow that disgusting man to the bathroom?? Like for reall?? Seriously???? Ffs. Idc
