She can save her enemy’s life by KISSING him, so he has to get her to fall in love with him

She’s a flower fairy for the Fae Realms and he’s the High Lord of the Moon Realm. They are destined to hate each other. Hundreds of years ago, he was the reason that many faeries died a painful death and has since been locked up for thousands of years. She accidentally helps him escape and he finds out that she can save him whenever she kisses him. The only problem is - she hates him. It’s up to him to get her to fall in love with him or else the Moon Realm will go extinct.
