Moonfollower's manga / #fantasy(1)

Lady x Duke A was reincarnated in a different world as the daughter of countryside nobles; she hears about a Saint who arrived from another world and excitedly travels to the capital to see her; B's desperately trying to keep the Saint away from him and ends up proposing a contract engagement to A for her to help get rid of the Saint which sounds like fun to A A really healthy relationship (a lot of grounded self-assurance from A and willingness to learn and grow from B; no toxicity whatsoever) 10/10
