1. Your bug
2. Mary gives you the potion even if you didn't talk to bunbun outside of the house(assume you don't mind bunbun outside, but go straight to rivals house), I think Katherine says the part why they didn;t marry that time too :<
3. After bunbun gives you tyrogue, retalking to him triggers the same event again, he gives you another Tyrogue. And wont just say run.
Other then those nothing really cathced my eyes :>
