Thanks for the hint! I feel like I still must be doing something wrong :P I've tried raising trust while keeping management as low as possible (never selecting "work at boutique" unless it's fixed in the schedule). I'm guessing that I'm still picking story choices wrong somewhere at the beginning, as I'm not unlocking most of the special romance scenes I saw in Zane's true ending when I attempt to keep management low. Ah well, I might move on to the other boys and come back when the walkthrough is released.
EDIT: Finally got it, after multiple tries! Also finished Kiron's route, and I'm SO excited to be moving on to Daire at last. Just one thing, a potential glitch perhaps? When I try to set the stats preference to "fast/skip", it always seems to reset back to normal and I'm never able to skip the stats on replays.
