I was kicked out of the party because our levels were different.

A mage was told by the hero to leave the party because their level was too low. However, according to a divine oracle, the demon king could only be defeated with these specific party members. The king had formed this party as a royal decree based on that prophecy. So why? After somehow convincing them and barely escaping with their life by the skin of their teeth, they make a promise to reunite at the last town and part ways. A hollow story where the protagonist is simply loved by all the party members. ※Boys love is insurance.
