some people are saying that sun-oh stole jojo from hye yeong but the thing is sun-oh asked hye yeong many times if he liked jojo or not but he denied it every time so you can't say that sun-oh stole jojo from him ¯\_(ツ)_/¯
i don't want to offend anyone and please don't get mad at me for saying this but i really prefer seojun over suho. at least seojun respects jugyeong for who she likes and don't get possessively jealous and mad every single time she spends with another male!! ( in suho's case seojun '')
