Hello! I've recently played your game (and i loved it!) and I came across a weird bug or glitch. Hana's hangout event with the normal outfit seems to stop altering the pink lock thingy after the third variation of the outfit (more precise, the "Let's get some drinks!! II" hangout event).
Edit; Whoops! I found out that it was only my mistake! (For her pink lock value to go up, I had to keep making her work at the canteen.)
Aside that, is there a fourth variation of her normal outfit?
