Short version is confinement and grape, MC goes out for a while to help his friends escape and get imprisoned when he returns, more grape, escape from prison with Kasha, Prince feels lonely without daily grape and follows him, MC’s life in danger so prince helps put out the threat, MC forgives him and they both go back to the kingdom even though the MC’s full fam and friends are now in Vera (basically MC gives up lifelong dream to be with prince, prince never really suffers, MC is just spineless)
I think the most popular comment spoils the entire story better if you wanna read it

And so it starts….goodbye everyone the best part of the novel is over
