Picrel, it's a fantasy comedy about childhood friends who meet up daily, with the caveat being that the boy is an adventuerer who has to go through an entire dungeon every time they want to meet, because the girl is the dragon raid boss at the end of it.
It's light-hearted, but can be very entertaining at times because there's a supporting cast of monsters who obsess over their relationship and come up with plans to push them closer together while projecting their own weird vices and perversions onto them. It also has a lot of meta jokes about anime and fandom tropes and the author even makes fun of the AoT Eren Yaeger "I DON'T WANT THAT" scene.
