anyone know if there is any bad side effect for using love potion? in description it says warning dangers...so i always sell to npc instead of using it,will it lead to any bad result in future or something? or i can safely use it?
The love potion has a negative effect on the relationship with a girl if you're not close enough with her yet. After reaching a certain value in the relationship with a party member gifts won't add to it anymore, then event and love option become the only option to increase it further. So they're actually rather valuable, just don't use them immediately on a new girl. ;)
