Maou no Ore ga Dorei Elf wo Yome ni Shitanda ga, Dou Medereba Ii? is a pretty fun read. Sure, it isn't anything groundbreaking but I still couldn't stop bingereading it. Basically, the main character, Zagan is former orphan that since then has become a powerful mage. In this world, magicians are considered evil, as they commit immoral things without second thoughts. Zagan wants to become a demon lord to increase his already huge power-level, but instead she meets Nephie, a beautiful orphan elf girl, who is being auctioned for anyone who is ready to pay a price. Zagan experiences love at first sight andorders her for one million gold coins, making him practically broke in progress. Then we are met with a wholesome love story where Nephie eventually falls in love with Zagan and they essentially become husband and wife while their family keeps expanding every now and then with more hilarious characters.

I think the major flaw of this series is that Zagan is practically a Gary Stu, who wins every encounter by default to the point that he isn't even devastated by any situation he and Nephie are in. But that's ok because the strongest part about this manga are the characters and interactions they have with each other. Plot itself isn't that remarkable, but it's more interesting to see how these characters react and act to any situation they are thrown into. And also Nephie's, Zagan's and later Fol's family dynamic is cute as hell.

I would recommend this if you need a manga that could put you in a good mood. Also bonus points for excellent art this manga provides.
