In korean, there’s a “C” at the end of the syllable, only “K” BUT in english people wrote it like “Taecyeon” although BOTH are okay. “Taecyeon” and “Taekyeon” is right, you can choose whatever you prefer better.
But Taecyeon himself spells it as Taecyeon not Taekyeon. You can’t just /choose/ which way you’d rather spell it if the man we’re referring to spells it one way, LOL. That’s just weird.
omg yes! he spells it taecyeon IN ENGLISH :)
