Books with extremely and ridiculously oblivious MC

Hi! I just finished reading Broken Ice by Marina Vivancos and I’m looking for similar recs. The MC1 Beau’s obliviousness is infuriating that I had to facepalm a few times, but it’s also surprisingly adorable?

Any genre or trope is fine with me as long as the MC’s obliviousness is on similar spectrum as Beau’s but I’d prefer some sort or height/size difference and my deal breakers are SA, cheating (in any shape or form), sharing/poly, abuse, third act breakup, or anything too heavy.

Thank you!
