MC is aggressively promoted to be RM’s flagship loveline. You can’t compare it to natural relationships between Ji Hyo and other members.
Kwang Soo said long ago Ji Hyo takes care of him like a grandma on set. She already treats him very well, as well as everyone else. Yoo jae Suk said Ji Hyo deserves a gold star for how well she treats her fellow members (ep 98). A staff member from the ShangHai 2013 dream cup shooting said:
“Someone worth mentioning will be Song Ji Hyo, even though she didn’t speak much, but she was especially meticulous and caring, when we were eating, she will always ask if the staff had eaten and will specially bring food to share with us”
Ji Hyo is a very nurturing person both on and off camera, we just don’t get it shoved down our throats with staged scenes and manipulative editing because It’s not one of her “characters” on the show in pd’s eyes.
