Looking for Josie manga where there is a very large age gap between the two main characters

Shuuden na kankei, it has only 2 chapters though

Otoko no isshou

Kore wa Koi no Hanashi

Koi wa Amaagari no You ni

Asami-sensei no Himitsu

Hotaru no Hikari

&

Bread & Butter

Gozen 3-ji no Muhouchitai
Piece of Cake
Kimi kara no Resume
Shigeshoushi
Sensei Ote o Douzo

Hope these work for you. You also might enjoy the benefits of using the advanced genre search and checking out the Age-Gap tag/category.
