Because of her dislike of socialising, as well as the fact that she heavily immerses herself in alchemy, Iris is out of tune from others. Right before her, a messenger from the castle appears.

Receiving a request from her kingdom to complete creating the illusory gem, the "Ritos", which has the ability to lift any curse, Iris finds herself perplexed.

She eventually decides to take on the request in order to prove that she is a skilled alchemist.

By meeting wonderful people and receiving assistance from her tutors, her positive feelings eventually blossom into feelings of love...

--They even begin to profoundly change her destiny.
