I like novels where the MC doesn't realize the ML likes him, but it's obvious to the reader that the ML does. I liked the dumb MC's in the stories below, I thought the MC was really cute but stupid. Befriending The Most Powerful Person The Villains All Fell in Love with Me After Rebirth Thanks.
Well I don't know about dumb but the most oblivious mc I have read about until now was Wei Wuxian from Grandmaster of demonic cultivation.....dude does not realise the other guy's in love with him until the 100th chapter. It's rlly funny too but the mc is kinda very clever, only dumb when it comes to noticing romantic feelings
Not a big fan of dumb uke, but here are some where the MC is pretty obvious A Guide to Raising Your Natural Enemy Glory
I think that easily 95% of the MCs of BL novels fall into this category. If anything, it's harder to find one that isn't oblivious... Anyway, gonna plug myself: Death Progress Bar
I dunno if it's under the tag of dumb/oblivious mc but u can try reading: You Can't be Fierce Towards Me The Young General's Wife is Mr. Lucky (Mc is a lucky koi who is reborn as a human) Daily Life if a Wealthy Woof (Mc is a dog that can transform to human) Hard remembering some bl novels I've read with same genre but u can binge read the summary first see if u like this ones.
everyday the protagonist wants to capture me so what if you've been reborn both are good BLs with oblivious protagonists
Welp here we go, let me pull out my rabbit MC inventory. I highly recommend the first three they seem to fit in your specifics. Don't You Like Me. Modern, supernatural and full of fluff, One of my fav ML's in danmei novels. Due to a misunderstanding the ML thought the MC was gay (the ML was) coz he's so touchy feely when in fact the MC was just using him as a ghost repellant. I Rely on Kisses to Clear Surviving Games. Horror game theme. The title says it all lol. Can't spoil it cause the mystery is part of the fun. If You Don't Fall in Love, You'll Die. Modern. MC is given second chance in life but has to do daily mission related to ML to survive. Everyday the Protaganist Wants to Capture Me. If you're into transmigration/wuxia. Recommending it cause it's near completed Misplacement Game. Same genre as the second recommendation. MC is a face con. Let Me Shoulder this Blame. World hopping, the MC is trying to clear the worlds by creating misunderstandings but the ML always steals the black pot from him. It’s Actually Not Easy Wanting to be a Supporting Male Lead. ML chases after MC through few worlds before they get together. The ML is a pig teammate that doesn't follow the script and made MC register to act in slash worlds to raise his pointa lol. The Target Always Think I Like Him! Also a good worldhopping novel. I Really Am a Slag Shou! Has similar feeling to TTATILH! The Strategy of Washing Clean a Slag Shou. Worldhopping. Angsty, MC dies in every arc. I've Lead the Villain Astray, How do I Fix It? Twisted black-belly younger brother X irritated wifey older brother. Transmigrating into a Demon Spirit to Blow up the Entire World. Worldhopping, MC starts off as non human in every arc, ML is always the pursuing party. Reborn as a Good Child. Rebirth novel in which MC thinks ML is in love with his older sister. ML's here not my fav but you might want to give it a go if you're into angsty beginnings.
