he's a coward and will choose yohan every time even when jun stood up for him, not in the sense that he likes yohan more than jun, he likes jun enough to approach him behind yohan's back (which is already a risk for him). Just as an analogy, IF he ever dated jun, he would be the first person to convince yohan that there's nothing between them, he would even denied jun if jun kept insisting that they're actually dating in front of yohan. That american guy is just that scared of yohan.
Still ig he's far more better than yohan ,its not like I hate yohan but I just think it would be great if that blond hair guy was 2nd lead . Idc if he's coward or whatever , but the least he's don't mean any harm to our jun
what in the hell I accidentally posted the cmt without correcting my typo mistakes & all . Sorry for my half baked opinion
Sometimes i really wish that American-korean guy was the 2nd ml
