I'll get the mandatory ones out of the way
Gotoubon was mostly good until Negi screwed it at the end, so, despite enjoying my time with it, I'd suggest avoiding it
Komi-san is the obvious go-to, but you probably already know that and/or have read it.
Please Don't Bully Me, Nagatoro is about a socially awkward loser and his Kouhai who tends to harass and tease him. No, she is not a tsundere, thank god. She will, however, get jealous if someone else tries to bully him, put an end to it if someone goes too far or insults/belittles him, and doesn't like it when he hangs out with the Art Club President. They have a great dynamic and she's very playful and enjoyable to watch as a character due to her reactions.
The Duke of Death has several couples that are very engaging and enjoyable to watch and get a lot of good chemistry and development.
My favorite, though, are usually kinda weird. (Note: I don't read Yuri so I won't be able to give my two cents on that.)
Yancha Gal no Anjou-san is a very good read-especially as there's no love rival up to this point and it's more focused on a character study between the two leads. The female lead is a Gyaru who loves to tease the main character, but deep down they're both insecure but genuinely care about one another and are willing to do a lot for each other-even if the other person isn't watching.
Kubo-san is a manga about a boy who is basically non-existent to everyone but the most popular girl in school, who is the only one who can see him. What develops can only be described as absolutely adorable
Kaiju Girl Caramelize
is a rarely-updated but much-beloved story about a girl who whenever she feels extreme emotions turns into a Kaiju. Cue her falling in love.
https://mangadex.org/title/24104/sono-bisque-doll-wa-koi-wo-suru seems to be a good read from what I have read so far, though that's not a whole lot. It seems to have a couple between a boy with a very niche-hobby of doll making (which as someone who paints minis is something I can respect) and how one of the popular girls ends up falling for him and his ability to help her look fashionable.
Asuperu Kanojo is a about a girl who runs away from home due to mistreatment and goes to live with the only person she can think of-a down-on-his-luck porn artist. (No, nothing lewd happens, as he makes it a point of principle later on.) What ensues is a good depiction of various mental health issues, a solid character study of the two and them trying to make their way in the world.
Abs Knight (not the real title but whatever) is the story of Fooly who is a young mage who falls for the most dangerous woman in the world because of her abs. I am not shitting you. It's sweet, but Fooly has to deal with constant thots trying to make moves on him.
Succubus no Hanashi has the main character be visted very night by a Succubus named "Lily" where she says that she can drain his vitality in exchange for whatever dream he wants. Instead of asking for lewd or perverted dreams, he instead asks for simple ones like being able to play video games or having a cat to play with. Slowly, she starts to fall for him.
My recently hired maid is suspicious (Alt)-A young kid and his maid which he thinks is up to black magic because of his feelings for her, and a maid with 0 defense and 100 attack. Comedy ensues
My Elite Senior Dame Knight Only Acts Cute to Me-Boy is the best guard of his age and falls in love with his senior officer at first sight-who proceeds to treat him as a joke. So, he proceeds to tease her everyday in order to try and win her heart
The Clueless Transfer Student is Assertive-Socially excluded girl + Socially inept and very honest boy = a recipe for a good time
Hitomi-chan is shy with strangers-pretty much what it says on the tin. It's kinda like Komi-san except less gag-based and Hitomi gives off more of a menacing impression to everyone but the audience
Ano Hito no I ni wa Boku ga Tarinai-the story of an eldritch horror and her boyfriend who get pursued by monsters. It's more wholesome than it sounds, but there is some nightmare fuel.
Ane Naru Mono-After his parents dies, a boy is forced to live in the home of his comatose uncle, who warns him never to go into the shed. He does, naturally, and finds a demon who says she'll grant him one wish before he dies. He wishes he has a family and so she turns into his adoptive "Onee-san."
Mato Siehi no Slave-In this universe, people disappear to an alternate universe which parallels our own at random. MC, who was trained by his big sister before she disappeared, wants his own harem. He ironically gets his wish in a way he didn't expect, as he gets "enslaved" by a member of the Anti-Demon Corps to ensure both of their survivals due to an ability she has. He gets his harem-except he's basically their property.
MobuSeka-A satire of Otome games/Isekais in which the main character is transported to the world of his sister's Otome after he dies playing it. He proceeds to utterly and completely tear the living shit out of how shallow the reverse harem is and breaks the game. As you can imagine, things get weird.
