A young couple Amarantha and Aaron get into a traffic accident. When Amarantha wakes up in the hospital, she finds out, that Aaron has lost his memories, including those of her.
The game will let you pursue four young boys, each one with completely different interests, personality, and approach. The hardest task, and also the “best” ending will be to try to get back Aaron’s memories and become his girlfriend again, since you’ll have to find out a way to restore his memories. However, depending on your actions, Amy could find out that maybe Aaron wasn’t the right man for her after all and fall in love with someone else instead, or she could also end up alone.
