Heartache 101: ~Sour Into Sweet~ is a freeware customizable Dating Sim created by flowerthief, previously known for Idolcraft. One day at school, Ferdinand agreed to a bet proposed by his childhood friend Miki, following a conversation regarding their respective skill (or lack thereof) at finding someone to date. Under the conditions of the bet, the two of them would be given 101 days to find and hold onto a significant other. If either of them were to succeed at these criteria while the other failed, they would be considered the victor. The game can be acquired for free at RPGMaker.net
