Once upon a time, in the year of 2012, a group named Btob has debuted. My bias was Peniel back then (actually all of them was). I stick to my bias until the early year of 2015, there was this who was casted as the second lead character in the recent drama called Who Are You, and he managed to ruin my bias list that I stan for almost 3 years just in blink of an eyes. And his name is Yook Sungjae. The end. Conclusion: yook sungjae ruined my bias list after stanning peniel for almost 3 years..
