Like I said. Throw at me ur best slice of life. I prefer romance with a male protagonist. Preferably with romance (no yuri Edit: shit I mean no yaoi ) and isn't include bland Japanese novels. Unless they are good
Back to the Sixties: Farm, Get Wealthy & Raise the Cubs though it’s female protagonist and a little long but it’s nice .
Otonari no Tenshi-sama ni Itsu no Ma ni ka Dame Ningen ni Sareteita Ken. Romance with male MC. JP novel but this one is veeerrryyyy cute and sweeetttt you're melting Tondemo Skill de Isekai Hourou Meshi. A JP novel, but it's more recommended to read the manga adaptation instead since people say it's getting too boring to read the novel. And I do enjoy the manga more too! Oh no romance fyi. Have a Meal Before You Go. A KR novel about a man getting back from isekai to find out that his world is already changed and he decided to open a restaurant. I consider this as a slice-of-life since it has a pretty easy-going plot (and I drool over the food...). Not sure if this has (or will have) romance, but it doesn't matter. I’m Really Not The Demon God’s Lackey. CN novel. I guess this doesn't count as "SoL" but MC's daily life is pretty much laid-back.... compared to his customers obviously... I'll recommend you some good SoL mangas too (though not all has romance) : Gakuen Babysitter. About a boy taking care of this little bro in a daycare affiliated to his school. You'll get drowned with the babies' cuteness you suddenly feel like a pedophile One Point Advice Yankee. A very enjoyable read about a yankee-looking man giving advice left and right. This one is pretty unique as the extra chapters are almost 3x longer than the real chapters. A must-read! Mr. Villain's Day Off. It's basically about an evil alien with a mission to destroy earth falling in love with pandas. It's a very interesting story. Sket Dance. A MUST-READ!! A comedic school life SoL manga, but this actually has a proper "plot" and ending. Completed since long ago, but still gold!! Horimiya. Highschool romance. I really like the interactions with their friends and other side characters; I guess that's what makes this a worthy read. Oh and I enjoy this one too: Another World Where I Can't Even Collapse and Die. Female MC, but this is very fresh as this is not your so-called typical isekai manga. Ice Guy and the Cool Female Colleague. This one is sooo cuteeee~!! You'll love MC's reaction whenever he's making advances to his crush. Hayaku Shitai Futari. A romance between a common girl and a boy with very strict rules in his family but he still strives to be a proper couple with his gf. Nan Hao & Shang Feng. Just read this
Most of the novels on this list are really good. I have also read some of them. Try these too. https://www.novelupdates.com/series/third-prince-elmer/ https://www.novelupdates.com/series/three-days-of-happiness/
