I have some question to myself. Why I write better when the character is not my bias? lol. Did any of you guys have the some problem with me?

For example VIXX Leo, I write a lot about him. When actually Jung Taekwoon is not my bias. His my best friend bias. but I tend to have a lot of imagination and story line regarding to him. Inside the story I can make him do cheesy, romatic stuffs. While when I write about my bias, my brain like freezing, I struggled a lot writing about my bias. hahaha
