Is the Sojiro confidant supposed to be this hard to rank up? I've got the correct persona, but I've met him like 4 times between levels 3 and 4 and still no sign of ranking up.
Should I wait for a story event or something or is this just a particularly long soul-link? Because the doctor, on the other hand, it feels like I rank up every time I go see her, and Ryuji is either every time or every second time.
Are you brewing coffee? If I'm not mistaken, it affects the social link progression.
