The Hero Falls in Love with Villager A.

The hero who defeated the Demon King fell in love with... a regular villager?! "I love you! Will you please date me with the intention of getting married?" The first town that adventurers visit is Guasi, where Ares, a regular person, lives. One day, Rolfe, the hero who defeated the Demon King and brought peace back to the world, visits Guasi and asks Ares out the moment they meet! Ares immediately rejects him, as this is not only their first meeting but he believes they're not suited to each other, but Rolfe continues to earnestly confess his feelings. Ares eventually gives in and agrees to begin things "as friends," but Rolfe keeps hitting on him with everything he has while he's staying in the village!
