https://www.mangago.me/read-manga/sono_gap_nyoi_special_feature/ anthology of gap moe oneshots (≧∀≦) very fun
When there's a drastic difference between outward appearance and their true personality. Gap meaning the drastic difference. Moe meaning the feeling you get when you experience that difference. Example. A mean Yakuza looking guy who blushes a lot. Or vice versa. A cute looking guy with a potty mouth.

Any fluffy yaoi recommendations? Something with gap moe would be the best
Thank you
