felix metioned i.n on dazed korea:
βwe asked him what his secret to always maintaining such a calm and gentle smile, felix just laughed. he smiles the brightest when talking about the maknaeβ
felix: βit's jeongin. i talk with i.n a lot. our jeongin, as a hyung, i find myself watching over him and taking care of him a lot, wanting to make him happier. when someone has worries or is going through tough times, guys would usually just leave it and think that they'll sort it out on their own. but jeongin is different. he's not the type to show it but if you watch him for a long time, you will notice. it shows. so that's why i tend to give him nice birthday gifts or joke around with him or have deep conversations with him. in that sense, we're close. he's really pure, that's why he's like a flower. it's like a flower might pop out of his head!β
