Okay so, I've collected the names of all the bls that have little to no smut, so let me list them in categories, and also, I have read more manga than manhwas, so there's gonna be a lot of manga listed
So first category is manga that have smut only in the bonus chapter:
"Suki tte Itte Kurete mo Ii yo?"
"Takara no Biidoro"
"Oaiko"
<3"Tonari no Metaller-san"
<3"Hidamari no Orange"
<333333"Punks Triangle" (chapter 6 and extra) (the best manga to ever exist in my opinion)
Manga that have smut in the bonus chapter and in the last chapter:
"Karasugaoka Don't be shy!!" (It has smut at the end of the last chapter in vol 2)
"Kiss wa Shita kedo, Tomodachi dayona!?"
"Unmei-teki Lovemeter" (in the last or second to last chapter there're allusions to suicide, there's a warning at the beginning of the chapter)
"Tell me you can hear it" (but you won't get flashed, there's no panels with dicks)
The manhwas that have smut in the second season, but the first season is so worth reading:
<3"The guildmember next door" (actually if you're planing to drop it after first season then not much happens in there, but there's not much smut in the second season, so if you don't mind that, then it's absolute peak, one of my favorite series)
<3"Involuntary romance" (the first season ends in a way that concludes everything and I honestly thought it ended before the second season was announced, so totally worth reading even without the second season)
Manhuas (tbh I read all of them some time ago and I believe they did the deed in every one of them,but it was short and so not explicit, it really felt like there was nothing there and that is the point with manhuas,bc they are Chinese and almost never contain any smut, so if you want to read smut free bls without worrying that someone recommend you wrong or smth, go for manhuas):
<3"I ship my rival x me"
<3"The Royal prince's first love"
<3"My Lover, Don’T Be Angry With Me"
Everything that has no smut in it (but if it's ongoing then I can't guarantee there won't be any smut in the future)
"Koi no ghost"
"Harinezumi to Contrast"
"The Unrecognized You"
<3"Behind the scenes scandal"
<3"Problematic leadership activities" (this one is on side stories and it seems like there'll be a scene with them doing it in the future, also my all time fav)
"Speak the truth"
"False memories"
"Don't touch me!" (I can't lie, it was a nightmare to get into it, but it was nice reading it as it was coming out, I don't think I would last for the whole story if I was reading at all at once tho)
"Don't throw stones at the stone bridge" (ig it's kind of a spoiler, so A SPOILER WARNING, it's not actually a romance)
"Bending the spoon"
<3"Romantic graffiti"
"From hate to fate" (honestly I haven't finished it yet, but from what I know there shouldn't be any smut in it)
"Merry marbling"
"Wild beast warning"
"Love is an illusion!-superstar" ( it's a sequel for "love is an illusion!!" Which has smut in it)
"I like your pheromones"
"Gambare! Nakamura-kun!!" (I recommend watching the anime instead of manga, the anime has some things cropped out and the manga was quite creepy in multiple parts, I know there are a lot of fans, especially of the anime, but as someone who read the manga I can't hide that I'm rather sceptical and scared of what the story will be like)
<3"The hunter wants to live quietly"
<3"See you, my king"
Now the ones that have sex scenes, but they are cropped in a way there's very little visible
"My sweet dear"
"Goshujinsama wa Ouji ga o Suki"
"Hana to usagi" (every chapter is a different couple, there are some without smut, the others are cropped as far I can remember)
<3"Error detected" (this one is truly cropped, nothing above the waist is shown, if there is they are wearing pants)
Lastly some bls that I couldn't classify
"A Midsummer Night's Kiss" (no smut in the main story)
<3"Cycling hit" (two last chapters)
<3"Namida no Tantanmen" (it's not even a romance, but it's a nice one shot about life and stuff)
<3"The otaku love connection" (it's a romance, but not a bl)
All of the recs I included don't need the smut, the bonus chapters or the last chapters, if you omit them, the story still is concluded and coherent, so although not all of them are completely without smut, they are still worth it
I also placed a heart next to each title that I absolutely love and have reread and recommend so much, these are absolute masterpieces
Also I'm sorry I talked for so long, but I wanted to give clear instructions, since when I use websites for recs or other people's recs, I most of the time don't know what to expect and get disappointed 99% of the time

Does this have smut???…genuinely wanna know before continuing im in like chap 8
