In B4 Love route I just met Azula and she gives you the chance to use a youth potion but then your (zuko and azula) daughter enters the room. I think I had potions left but I can't check, and Shady isn't there (at least yet) will I be able to buy potions? or should I save it? (because it would be wasted)
Edit: Oh man, I can't stop laughing at Pema teaching mc how to wear a condom. For how it ended, but also because she herself says she only took interest in contraceptives after harmonic convergence.
Edit 2: After you pay your debt to Shady (30 coins) you can buy them.
