あなた go onto their プロフィール and click "become a fan". It should be on the left side

first of all welcome :D second. if あなた go to somones profile, scroll down until あなた reach the bottem where it usually ends によって the fav book. right underneath it, it says Be a ファン (or somthing like that) click it and TA-DA ファン ^^

click on someones useername and you'll go to their プロフィール and stuff scroll down and it gives あなた a 一覧 of things あなた can do at the bottom of the プロフィール it has a plus sign and says add ファン または something along those lines, click on that and あなた added someone as your fan.
